From Dom DeLuise's obituary at an ABC website:
Meanwhile, actor Gene Wilder gave the pudgy funster rolls in The Adventures of Sherlock Holmes' Smarter Brother (1975) and The World's Greatest Lover (1978). And Mel Brooks' wife, Anne Bancroft, finally gave DeLuise his own roll in 1980's Fatso.The first "roll" could be a typo. The second makes it a stupid mistake. From a writer who got paid. My eyes roll.
(No, I don't accept that it's a pun on his weight.)
