Captain America: Civil War

“United we stand. Divided we fall.”

Steve Rogers (Chris Evans) wants to operate without oversight, but Tony Stark (Robert Downey Jr.) has decided the Avengers need UN supervision after collateral damage in their last mission. The two men split the team in half, each convinced the other is wrong, and what began as a disagreement becomes a fight. By the end, Steve and Tony are no longer allies, and the fracture between them shapes everything that comes after.
