I can't see any possible reasonable reason to remake this film whatsoever.
It's a fine enough film as it is.
What's to change?
Do they need to add flashy special effects for a 'modern audience'.
I've see this term bandied around a lot recently, where TV or film production tries to flog something to us by claiming something's being made for a 'modern audience'.
Which often tenRAB to result in the finished product being about just style and zero substance, and a very poor end result.
