9. Robin Williams
Robin Williams hyperactive blend of physical comedy and non-stop riffing has given him a near 40 year career at this point. From his early beginnings as the lovable alien Mork to his latest incarnation as a Catholic priest in the abortive comedy The Big Wedding (never mind that he played a reverend a few years earlier in an equally unfunny turn in Licence to Wed), Williams antics have been hated as much as theyve entertained. Except he hasnt been in a good movie in years. Look at his output of the last 15 years: Old Dogs, Night at the Museum 1 and 2, Happy Feet 1 and 2, Shrink, Man of the Year, RV: Runaway Vacation, Robots, Death to Smoochy, Patch Adams, the list goes on they are all utter crap. Couple that with his tired old stand-up routine he did a while back, Weapons of Self Destruction, and it makes you wonder what anyone saw in Williams to start with. Have you gone back to re-watch some of his classics, like Mrs Doubtfire or Hook? Hes not good in either! His funniest performance is arguably in Good Will Hunting. If you see Robin Williams in the cast of a movie these days you know itll be an unfunny and kinda terrifying experience to watch. And if you do end up watching one of his movies, you inevitably want to hit him every time he shows up and riffs his way through a scene. At this point in his career, hes become a living cartoon of himself.
