He does remember being top billed, probably paid the highest salary, had the most screen time, got no slime on him, and had an unorthodox amount of say regarding production i.e. if he didn't like Kurt Fuller, he'd be out of the movie. I wonder if ever there was a time when Reitman or an executive told him to shut up and do the job he was paid to do.
I don't see why he gives GB2 so much flak. Aykroyd and Reitman don't understand it either, something they have made clear over the years. It's not like he hasn't made some duds in his career. What was the name of that elephant movie he was in?
GB2 is 32 years old today and it's the last of its kind regarding the original four. If he wanted it to be better, maybe he should have used his pull to ensure the script didn't change instead of securing creature comforts.
