I like this movie but I hate to admit I laugh when Marley screams in anger at Scrooge.

I know it's meant to be freaky but somehow the actor just sounds a bit funny to me when making that yell. Also when Scrooge says that if it were up to him everyone who said Merry Christmas would be boiled in his own pudding and buried with a steak of holly through his heart, I find it funny only because of Scrooge laughing while saying it. I somehow find the line more intimidating sounding coming From Michael Caine in the Muppet Christmas Carol. Still like the movie though.
