Uri Geller seems to have lots of show-biz friends, so I don't know if he and Ken were friends. But the film does seem like a vanity film, very crudely glamorising Uri. There are a few good images, but overall it is a very boring film with poor acting, script and direction.
And it does end with the real Uri (as distinct from the actor) trying to do one of his tricks to the viewer- it didn't work for me.
