Actually, Denholm Elliot made it pretty clear that he believed Marcus was written more as comic relief in order to cede ground to the Henry Sr. character, who was playing the mentor role in the context of that story.
That said, I believe the old Marcus is still very evident in the scene where he and Indy find Henry Sr.'s office ransacked. "I'll tell him we'll take two." He is then immediately a bumbling character in the next scene. Of course, Elliot is such a great actor it doesn't matter.
