Can't see any brand, but it does say 3850, that's a start...

Here is a larger picture of the number.

Also, almost every cellphone from the movie franchise scream is in the unknown section on http://www.phonesinmovies.com/

Wich makes me think it's custom made.

Thanks rundown
It seems to be more difficult than I thought if it's a custom made and I think you're right.
Your screenshot is pretty good anyway.
