We've already seen when actors completely can't be bothered to put in a performance, and when actors admit they only did films for the paycheck, but what about when things get even more serious?
Some famous Hollywood names have taken to the courts in a bid to stop their films from being released, usually early stuff they've done for the money.
So which famous names really didn't want us to see them before they hit it big?
6. Madonna in A Certain Sacrifice
A pre-fame Madonna Ciccone featured in the 1979 drama A Certain Sacrifice, written and directed by Stephen Jon Lewicki
Madonna was behind on her rent and asked Lewicki if he would pay her for her role.
The director required her to sign the release to get $100 in order to get the money (which would come back to bite her in the backside).
Fast forward to 1985 and releases Like A Virgin and Material Girl catapaulted Madonna to become one of the biggest stars on the planet.
To capitalise on the popularity of the singer, A Certain Sacrifice was lined up for a video release and midnight screenings in cinemas.
The Material Girl was outraged and tried to buy the rights from the director Stephen Jon Lewicki for $5,000.
Lewicki refused and she tried to have the film banned from being released, but Lewicki used her signed release to prevent the film's ban.
5. Sylvester Stallone in The Party at Kitty and Stud's (changed to The Itallion Stallion)
Sly's first film was the softcore porn film in which the starving actor was paid $200 for his two days work back in 1970.
Stallone has said that he had been kicked out of his apartment and was sleeping in a bus station when he took the role of the oafish Stud.
He explained: "It was either do that movie or rob someone because I was at the end, at the very end of my rope.
"Instead of doing something desperate, I worked two days for $200 and got myself out of the bus station"
In 1976, after Slallone became a household name from the success of Rocky, the movie was re-released as The Italian Stallion in order to ride Sly's wave of popularity.
Stallone claimed the film was financed by "a group of wealthy lawyers," and when he tried to block the release of The Italian Stallion, its lawyers asked for $100,000.
Stallone said he "wouldn't buy it for two bucks" and the film was distributed to movie theaters for $10,000 a night.
When Stallone heard, he commented "Hell, for $10,000 forget the movie! I'll be there myself!"
4. Mel Gibson in The Million Dollar Hotel
The film's story was conceived by Bono (which didn't start any alarm bells ringing) and starred Mel Gibson and Milla Jovovich.
A run-of-the-mill whodunit set in a run-down hotel in Los Angeles, The Million Dollar Hotel pulled in $29,000 in its first weekend (from an estimated $8 million budget).
While promoting the film in Australia, Gibson, said he thought the film was: "as boring as a dog's ass."
He later tried to explain his words:
"It was at the end of a day where I had done 6,000 interviews, some guy was ragging on the film and it just slipped out.
"Later, I thought 'God, why did I say that? I'm an idiot! I produced this film. I'm distributing it!'
"It was pretty thoughtless of me, because a lot of people worked very hard on that film, and the fact is there are moments of genius in it.
"The soundtrack is by U2, and it's phenomenal. So I really regret saying that. I have written a lot of apology letters about it.
Despite that Gibson tried to prevent it being released in the US, but managed to get it down to a limited release.
3. Robin Williams in Can I Do It 'Till I Need Glasses?
Comedy legend Robin Williams' first film was the 1977 extremely un-PC sketch comedy, which was a follow up to If You Don't Stop It... You'll Go Blind (hence the sequel's title).
The film originally didn't feature any of Robin Williams' sketches, but off the back of his Mork & Mindy success and his 'debut' film Popeye's release in 1980, the film was re-released
The new version saw the comedian's name feature heavily in the promotion despite him only appearing in two scenes.
Williams was very happy about his name being included and sued the film's producers over his appearance.
Reportedly the case was settled out of court for $5 million - or approximately 1.25 million per minute of time Robin Williams appeared on screen during the re-release.
Subsequent releases of the film have re-edited out William's scenes.
2. Matthew McConaughey in Texas Chainsaw Massacre: The Next Generation
The 1994 Texas Chainsaw Massacre: The Next Generation is confusingly both a remake and (sort of) sequel to 1974's Texas Chainsaw Massacre.
Matthew McConaughey stars as Leatherface's older brother, who also has a robotic leg
The film also features a young Renée Zellweger as a victim of Leatherface and McConaughey, before [SPOILER ALERT] his character is beheaded by an 'Order of the Ulluminati' plane.
The film, originally titled The Return of the Texas Chainsaw Massacre, had its release held back to 1997 for both young actors to land roles in big films.
McConaughey, not wanting his increasing name to be associated with a terrible horror B-movie, started putting pressure on them not to release the film.
Eventually the film was given a limited release in 20 US cities was eventually released on DVD in 1999.
1. Leonardo DiCaprio and Tobey Maguire in Don's Plum
Back in 1995, a 21-year-old Leonardo DiCaprio and a 20-year-old Tobey Maguire featured in the low-budget drama Don's Plum as a favour to their aspiring director friend R.D. Robb.
The black and white film features a group of teenagers hanging out and telling crude jokes in Los Angeles diner, Don's Plum.
Leo and Tobey agreed that the film wouldn't be released, but would be shown in film festivals
Then, in 1997, when Titanic made a global star of DiCaprio, Robb started talking to distributors to get the film a mainstream release.
When DiCaprio, Maguire and the rest of the film's cast discovered this, they attempted to block the film's release.
R.D. Robb claims that DiCaprio used his sway in Hollywood to prevent anyone from doing business with him, and eventually got the courts to block the film's release.
The courts ruled that the film can't be shown commercially in the United States or Canada, but was released in Europe and Japan in 2001 and 2002.
Here is a scene from the film, which will make you wonder why they were even that bothered about anyone seeing it, because no-one would have paid to watch it.
