I recognize the need to generate income by repackaging--publishers do it all the time, but the text is left intact. Here is a short list of some film remakes in which the "text" is altered, besides A Christmas Carol or Scrooge or Old Man and the Ghost, whatever they want to call it:
The Philadelphia Story/High Society: Here is a perfectly good movie with excellent casting, and someone goes and messes it up with bad casting and color. And who decided that adding music makes a film better anyway?
The Shop Around the Corner/You've Got Mail: I think the remake is kind of cute, but the original was so much more than cute. The characters had depth, and the boss wasn't a bad guy. I hate movies that make the boss out to be bad just because he's the boss and has money. It's a small mind that thinks so flatly.
The Parent Trap/The Parent Trap: I'll give them this one. I didn't care for the first one, and I thought its casting was sluggish. But really, what a ridiculous premise. How could an otherwise loving parent choose a baby and let the other one go without a second thought. Again, flat character.
Miracle on 34th Street/Miracle on 34th Street: Lovely black and white Christmas film that didn't need remaking, and the postal solution at the end made sense. The new version was not a bad film, because Maura was so cute you could pinch her face, but the In God We Trust solution was weak. If you can't improve on the original script, then leave it alone.
The Bishop's Wife/The Preacher's Wife: Hint, don't redo something Cary Grant has done so perfectly. Denzel Washington is a delight, but still, the movie was too lovely the first time to think you could make it better a second.
The Lady Killers/The Lady Killers: the second was nothing but an abomination. I was so happy when they killed the foul mouthed guy. Every time he opened his mouth to deliver a line, I cringed.
Others that were not improved by making them twice: Cape Fear, Psycho, Invasion of the Body Snatchers, Sabrina, Poseidon.
Have I forgotten anything?
