Pink Panther.

Matt, of course, you could do Peter Sellers in The Party, too. But Inspector Clouseau always had several dialogue sides per Pink Panther movies that were definitely mangled English.

Yes! The Return of the Pink Panther: the ”Do you have a license” routine.

@Josh: Revenge of the Nerds! Wow, I haven't thought about that for years. Timothy Busfield of thirtysomething, West Wing, and Field of Dreams fame is in that movie. And Robert Carradine was in the ABC pilot for K-9. Definitely Daily Dialogue worthy, thanks.

I always enjoyed Fenster in The Usual Suspects: "Hand me the fucking keys, you cocksucker, what the fuck?"

This theme is actually turning out to be pretty entertaining, isn't it?

It's not totally mangled, but I love how Olaf sings the song.

Know this isn't exactly fitting with the remit (in about ten different ways!) but can't resist posting it...

In a hardware shop. Ronnie Corbett is behind the counter, wearing a warehouse jacket. He has just finished serving a customer.

CORBETT(muttering): There you are. Mind how you go.
(Ronnie Barker enters the shop, wearing a scruffy tank-top and beanie)
BARKER: Forkandles!
CORBETT: Four Candles?
BARKER: Forkandles!
(Ronnie Corbett goes to a box, and gets out four candles. He places them on the counter)
BARKER: No, forkandles!
CORBETT (confused): Well there you are, four candles!
BARKER: No, fork 'andles! 'Andles for forks!
(Ronnie Corbett puts the candles away, and goes to get a fork handle. He places it onto the counter)
CORBETT (muttering): Fork handles. Thought you said 'four candles!' (more clearly) Next?
BARKER: Got any plugs?
CORBETT: Plugs. What kind of plugs?
BARKER: A rubber one, bathroom.
(Ronnie Corbett gets out a box of bath plugs, and places it on the counter)
CORBETT (pulling out two different sized plugs): What size?
BARKER: Thirteen amp!
CORBETT (muttering): It's electric plugs, electric bathroom plugs, we call them, in the trade. Electric bathroom plugs!

Snatch (2000)

Brad Pitt's character Mickey
(There was a problem with Pikeys or Gypsies. You can't really understand much of what is being said. It's no Irish, it's no English, it's just... well, it's just Pikey.)

e.g.

http://www.youtube.com/watch?v=D-0_sL5AAVQ&feature=related

Turkish: Well, do you want to do it?
Mickey: That depends.
Turkish: On what?
Mickey: On you buying this caravan. Not the rouge one, the rose.
Turkish: It's not the same caravan.
Mickey: It's not the same fight.
Turkish: It's twice the fucking size of the last one.
Mickey: Turkish, the fight is twice the size. And me ma still needs a caravan. I like to look after me ma. It's a fair deal. Take it.
Turkish: Mickey, you're lucky we aren't worm food after your last performance. Buying a tart's mobile palace is a little fucking rich.
[Realizes his mistake]
Turkish: I wasn't calling your mum a tart. I just meant...
Mickey: Ah, save your breath for cooling your porridge. Now, look...
Mickey: [starts talking incoherently] I want the hector two roof lights, with the discover cushions and the matching side stripe caravan.
Mickey: Right. And she's terrible partial to the periwinkle blue, boys. Have I made myself clear, lads?
Turkish: Yeah, that's perfectly clear, Mickey. Just give me one minute to confer with my colleague.
[to Tommy]
Turkish: Did you understand a single word of what he just said?

How could I forget Star Trek's Chekov:

STIV: The Voyage Home
Chekov: [to a street cop] Excuse me, sir! Can you direct us to the naval base in Alameda? It's where they keep the nuclear wessels.
[He pauses, looks at Uhura, and tries again]
Chekov: *Nuclear wessels*
