You can see at the end that Pleakley shows his alien form when someone hits a button so I am guessing they will have human disguises for parts of the movie because it’s harder to dress up and alien to look human in a live action movie when the animated one just had them put on a hat and sunglasses.

I’ll withhold judgement until I’ve seen the whole movie but it looks like they captured the important parts of the original. Not gonna become a classic like the original but I’m sure it’ll be fun for the kids and at least possibly entertaining for the adults.
