He was waving to imaginary people and even bent down like he was talking to a child

This A+ list mostly movie actor who is really close to an A+ list director comes from an acting family.

He also has a substance abuse problem of which we are all aware.

Apparently it has reached a new level.

While visiting troops in Germany, our actor had a ten minute walk through a mall to a movie theatre and was waving to imaginary people and even bent down like he was talking to a child but there was no child there.
