Well im playing my game on a laptop and its not the best one around, so everytime a movie comes up (ex. entering underdark) the game crashes and I cant go on.. so my question is: is there any way of shutting of the movies?

u might be able to do that on the configuration menu, im not sure.

I have tried that... could someone tell me where in the baldurs gate folder the movies are located?

You could always try a reinstall of the game, that should solve your problems.
Are you fully patched, Bioware and Baldurdash?
