That the character is such a compelling part of the film, given his convoluted origins in Marvel comics, is nothing short of a feat. It’s impossible to imagine the film without Sentry — but early drafts of Thunderbolts* didn’t include the character at all. He later remembered the Sentry comics he’d read when he was part of the Marvel Writers program in the 2010s. Thunderbolts* director Jake Schreier read a lot of Sentry comics in preparation for the film, including Jenkins and Lee’s run. In the film, Sentry and Void occupy the same body, and Bob’s amnesia manifests when the latter persona takes over.
