Worst accent has to be Brion James attempting an English accent in Tango and Cash. He sounded something like an Australian with terminal throat cancer.

Someone mentioning James Doohan reminded me of an interview with him I read in a magazine years back - he was talking (among other things) about how they’d considered various different ethnicities for the engineer character in Star Trek. AFAIR it went something like this :-
"So, when Captain Kirk shouted ‘Scotty, I want warp eight now!’, instead of hearing ‘But, Captain, the dilithium crystals cannae take it any more!’, you would have heard ‘Si.’
"Or " (Australian) "'Now look ‘ere, Captain, I’ve taold you I don’t like to gao faster than warp six. Oh, that’s an order. Well, orl right.’
"Or " (French) "'Ah, ah, ah, mon capitaine, you are 'aving ze joke with me, non? Also, back on ze planete, I notice you did not get ze girl… you should ‘ave stuck with lucky Pierre.’
"Or " (Long John Silver) "'Ah, ye be young Kirk, arrr? Well, belay that nonsense, or I’ll see ‘ee hanging from the highest yardarm in Starfleet.’
“Or my favourite would be Reggie, and he would say something like " (very, very English) “'I’m terribly sorry, sir, but I’m afraid I can’t get the little buggers to move along any faster.””
(If I’ve disillusioned anyone who thought James “aye, the haggis is in the fire fer sure” Doohan was genuinely Scottish, my deepest apologies.)
