There are plenty of hack directors, harsh filming locations and hokey scripts waiting to push actors over the edge, cheesy cinema that makes them question why they chose a career in show biz.
Sometimes a young star bites off more than they can chew when they agree to be involved in a project, like when a 36 year old Greta Garbo decided to star in Two-Faced Woman, the film she called "my grave".
The cheesy comedy stars Garbo playing a woman who tries to seduce her husband by pretending to be her own twin sister, and needless to say the critics were not kind.
The role left Greta so embarrassed she never made another movie, and when she was given an honorary Oscar fourteen years later she didn't even show up at the ceremony.
Even a movie industry veteran like Gene Hackman can find themselves involved in a project that is so beneath their talent level it pushes them over the edge.
Welcome To Mooseport is a steaming pile of cinema that closed the curtain on Hackman's movie career, a campy comedy starring Ray Romano that Hackman said he starred in "for the money".
The movie was a total flop and closed the curtains on Hackman's movie career, talk about a fall from grace!
