Actor/Actress with the Most Impeccable "Nerd" Credentials

Nobody mentioned Jon Favreau? He's like total King of the Nerds with his work in MCU and Star Wars alone, but also acted/produced/voiced in Batman Forever, Swingers, Buzz Lightyear of Star Command, Dilbert, Daredevil, Elf, Robot Chicken, Clone Wars, Zathura (video game), The Orville, Young Sheldon, the Shannara Chronicles. Listing all his credits for Star Wars related things and MCU would take up half the thread.

Also, not one mention of Mark Hamill either? Not only his Star Wars work but his voiceovers and video game credits are quite lengthy.
