Definitely would have to cut parts and make serious edits if they made a remake of the original instead of the upcoming sequel, but Beetlejuice.
The slit wrist joke would definitely be cut. The ghost advisor woman who smokes through her neck would most likely be on the chopping block due to the decline of smoking. The scene where Beetlejuice is stuck on the diorama and goes to the hooker/strip club(?) would probably be out. And the scene that would without a doubt be completely removed or reworked entirely no questions asked in a modern remake would be the scene with the centuries old creep Beetlejuice trying to marry an underage teenager.
