In Monkey Shines (1988), Jason Beghe plays a paraplegic who recieves an experimental helper monkey – an EVIL monkey.  I remember seeing the movie on TV and halfway watching it.  I don’t know that the sponge bath scene was in there when I saw it, I’d probably have remembered that.

I think To Have and to Hold was a TV series from 1998 where he played a detective of some sort.

And I’ve no idea where this came from
