What would Thunderbolts* be without Bob (Lewis Pullman)? While Marvel’s scrappy bunch of anti-heroes banded together to save the day, they in turn were saved by Bob’s innocence. So, after the lineup for Avengers: Doomsday was announced, the Thunderbolts’ presence in the Robert Downey Jr-led movie became even more meaningful. Fans are now eager to see what happens when Bob’s alter ego aka the Sentry, comes face to face with Doctor Doom (Downey JR), and Pullman has some ideas.
