Oscar Isaac as Llewyn Davis in Inside Llewyn Davis
Biggest challenge: Engaging audiences with his talent, both as a musician and an actor, despite being an relatively unknown name.
Biggest scene: As his frustration with his dead-end music career, his absent first love, and the death of his partner comes to a head, Isaac's Davis goes on a scathing rant during a dinner party hosted by his friends.
Why the peformance might get ignored: In a year crowded with excellent performances from A-list actors, and despite the fact his acting ability proves he'll definitely share the category with DDL in the future, anyone suggesting his nomination might get a "Who?" in response.
DDL says: "Someday, I think you and I are going to have a serious disagreement."
