Bradley Cooper
Despite his long career in Hollywood, Bradley Cooper's most important project was definitely 2018's A Star Is Born. He directed, starred, and even sang in the film. Even though the film won massive critical acclaim, and Lady Gaga scored an Oscar win, Cooper was only nominated.

After a string of lighthearted and comedic roles, Cooper was cast in Silver Linings Playbook, a drama alongside Jennifer Lawrence. This was one of Hollywood's first glimpses of Cooper in a genuinely deep role, and it launched him into taking more serious films. He also played Navy SEAL Chris Kyle in the biopic, American Sniper.
