Wikipedia All-Stars: Sean Connery

This might just go down as one of the single worst decisions of all time, and is apparently responsible for the end of his acting career:

Connery stated in interviews for the film (included on the DVD release) that he was offered a role in The Lord of the Rings series, declining it due to "not understanding the script." CNN reported that the actor was offered up to 15% of the worldwide box office receipts to play Gandalf, which had he accepted, could have earned him as much as $400 million for the trilogy.^[22] After the series went on to become a huge hit, Connery decided to accept the lead role in League of Extraordinary Gentlemen, despite not "understanding" it either. In July 2005, it was reported that he had decided to retire from film-making, following disillusionment with the "idiots now in Hollywood" and the turmoil making the 2003 film.

I hope to one day make a mistake thats costs someone 400 million dollars.  Thats the kind of thing you can put on a resume.  If there was a hall of fame for epically bad movie decisions, this would be in there for sure.  Right up there with the idea to make a movie about a killer tornado and have it star Bill Paxton.  Or pretty much anything that stars Bill Paxton.
