It very well might be Guber. Haim and Feldman were very active in Hollywood when Guber was a real power player. Gruber made a lot of box office hits, including Batman, which is the 2nd highest grossing film of the eighties(after Return of the Jedi). Whoever it is, I hope he’s outed soon. Drain the Hollywood swamp.

So you can't really decide how the name is spelled?
