Scott Pilgrim vs. the World (2010)

Scott Pilgrim plays in a band which aspires to success. He dates Knives Chau, a high-school girl five years younger, and he hasn't recovered from being dumped by his former girlfriend, now a success with her own band. When Scott falls for Ramona Flowers, he has trouble breaking up with Knives and tries to romance Ramona. As if juggling two women wasn't enough, Ramona comes with baggage: seven ex-lovers, with each of whom Scott must do battle to the death in order to win Ramona.

The four cast members that made up the band "Sex Bob-Omb" spent several weeks learning how to play together as a band. Mark Webber, Alison Pill, and Johnny Simmons all had to learn their instruments from scratch, while Michael Cera had to "dumb down" his bass playing in order to not outshine his band mates.

Near the end, when Scott sits on the swing with his sister, she calls him "little brother." Stacey is 18; Scott is 22. This is a repeated line from the original comic, where Stacey is seen as more mature and "older".
