Even though "King of the Beach" was Lou's first speaking role, Lou did have some acting experience playing opposite Bix. In the hypnosis sequences in "Married" Lou and Bix are face to face in the same shots, something that Ken Johnson had wanted to do for awhile. Of course since Bix and Lou were actually the same persona, this was something that had to be imagined in the mind of David. Or in the case of "Metamorphasis", drug induced halucinations experienced by both David and the creature.

In reality, Bix was often on the set on those days they were shooting "Hulk" sequences, even though he wasn't on the shooting schedule. I'm sure it was during those times that Bix would be there to give Lou advice and encouragement.
