The closest anyone could get to pulling off Neilson's schtick would be someone like Alec Baldwin, Geoffrey Rush, Liam Neason, or Tommy Lee Jones; basically an old guy who is not above playing a lampoonish straight man version of themselves. Even then, it would be miles off target and would not work right with this IP. Ed Helms? Not a fucking chance. He is all the bad parts of Steve Carol and Jason Sudekis merged together. Its like they decided even Will Farrell or Dan Akroyd were beneath this shit. Fuck them for even trying.
