What actor do you think would make a really bad james bond?  

I really have no Idea as to who will be bad, but I do know who can be the best. I think James bond is James bond because of Sean Connory. Even pierce Brosnan seemed to be great in the role. Now the latest heart throb, Craig Daniel is also good even though I still didn't give him personally a 'best' rating.
Happy Lotting

i am not so much introduced to english movies but in bollywood , the worst james bond will be salman khan as these roles do not suit him. he is a lively actor and he is full of enjoyment and shoutings and dancing so to seehim in this role will be difficult for me to believe.

Let's see...Not saying that I don't like these actors, because I do, but here is a list.
Jack Black
Samuel L. Jackson
Maybe Gary Oldman
Seth Rogen
Robert Pattinson
Tom Hanks
Jackie Chan
Jim Carrey
Adam Sandler
Jimmy Fallon
Sylvester Stallone
Steven Seagal
Robin Williams
Johnny Depp

i would like to see billy ray cyrus try out for James Bond, suddenly the others start to look good.
some people would actually enjoy jim carrey's version, but nobody would even dare suggest david hasselhoff....would they?

Hi jen, well I haven't seen a james bond film in years as don't enjoy them but as the classic james bond character created by ian Fleming was based on a suave sophistacted type of character who I believe was English then it would be best to have an actor who has none of these qualities at all to play a bad james bond so I would suggest Danny de Vito, much as I like him he's no James bond.
