Accents (that are not of your native tongue) can be tough to do. If you can nail in spot-on, then by all means go for it. If not, sometimes it's just better not to try. This thread is devoted to all of those who tried... and failed miserably.
Kevin Costner - Robin Hood: Prince of Thieves (the English accent is barely there but you can hear him make a few attempts at it from time to time)
Ewan MacGregor - Deception (worst attempt at a New York accent I've ever heard)
Jeremy Irons - Appalooza (half-assed attempt at an American Western accent)
Sam Worthington - Terminator Salvation (drifts from American ghetto-thug to Australian to Austrian, maybe? All I know is that it sounded ridiculous in many scenes.)
Patrick Wilson - Phantom of the Opera (terrible attempt at a French accent)
