Thunderbolts* features a diverse cast of characters, headlined by Florence Pugh (Yelena Belova), Sebastian Stan (Bucky Barnes / Winter Soldier ), David Harbour (Alexei / The Red Guardian), and Julia Louis-Dreyfus (Contessa Valentina Allegra de Fontaine).

Marvel fans seem to think they know the meaning behind Thunderbolts ' asterisk. Inspired by the comics of the same name, the upcoming MCU blockbuster tells the story of a group of Marvel anti-heroes, who are brought together for a high-stakes mission by government agent Valentina Allegra de Fontaine ( Julia Louis-Dreyfus ).

Someone is trying to kill Marvel's antiheroes. Can they work with each other instead of beating the heck out of each other to survive? Thunderbolts* (a curious asterisk included in that official title) gets an extended trailer debut Monday that runs a bit longer than your average movie preview.
