We have all had a moment or two when we come to a crossroad in our lives. In Hollywood, these can be 'make it or 'break it' decisions. Luckily, for most of the actor's on this list, their careers still flourished. But, imagine the dynamics had they accepted the offer to play key characters in the following movies.

So, sit back and think how some of these movies could have been with the following actors, who all decided to pass on some very iconic roles.

    James Bond (Dr. No)

    Call me 'old school,' but when it comes to James Bond, I am a forever fan of Sean Connery. I honestly can see anyone else in the role, even though the mantle has been passed to; Roger Moore, Timothy Dalton, Pierce Brosnan and now Daniel Craig. But think about how Bond would have been had Cary Grant actually had accepted the role of 007. Grant was Bond creator, Ian Flemmings' best man at his wedding and was thought to be the perfect choice.

    Sundance (Butch Cassidy & The Sundance Kid)

    Ego's run wild in Hollywood sometimes and a clash of egos is what happened to make Steve McQueen turn down this role. The only reason McQueen said 'no' is because his costar, Paul Newman, refused to give him top billing in the film.

    Vincent Vega (Pulp Fiction)

    Michael Madsen was in long drawn out rehearsals for the film 'Wyatt Earp' and wasn't able to participate in Quinton Tarantino's edgy and intense movie. Bad luck for Madsen, but good luck for John Travolta. Travolta had dropped of the Hollywood A-List radar, but this put him back on top and made him one of the most bankable actors.

    Neo (The Matrix)

    Personally, I can't see Keanu Reeves in any movie. It's safe to say I am not a huge fan of his. But he did have a successful run in the Matrix trilogy as Neo. Reeves was not the first choice though. Will Smith turned down the role, so he could work on the now forgettable movie, 'Wild Wild West.'

    Gandalf (Lord of the Rings)

    This may have been the biggest blunder on the list. Not because the actor who turned down the role didn't have an outstanding career, but because of the money he lost out on. Sean Connery was offer the role in the Lord of the Rings trilogy and also would get up to 15 percent of the worldwide box office receipts. I'm not trying to pour salt in the wound, but the first movie, The Fellowship of the Ring, pulled in 861 million dollars worldwide.
