I'm glad he did because as much as I love McBride he just has the wrong energy for the Alan part. I assume that's the part he turned down.
Thinking about one of the line readings I can see McBride saying the lines ibut it just wouldn't work nearly as well:
Alan: It's not illegal. It's frowned upon, like masturbating on an airplane.
Stu: I'm pretty sure that's illegal too.
Alan: Yeah maybe after 9/11 where everybody got so sensitive. Thanks a lot, Bin Laden.
Plus McBride is several inches taller than Zach and stuff like the police station taser scene wouldn't work nearly as well.
