When you say the words “Rocky” and “boxing” together, you think of one of two things: Sylvester Stallone, or how much you want to see Creed again right now. Jeremy Renner would like you to forget about all of that, and in a bid to get in on some of that Cash with a capital C, the actor is banking on your interest in boxing movies featuring guys named Rocky, or maybe he just hopes to confuse you into seeing his next movie.

THR reports that Renner is set to star in a biopic about the life of legendary real-life boxer Rocky Marciano — no, not Stallone, that other boxer named Rocky. It’s a lot to keep up with, we know. The star of The Hurt Locker and the MCU will play Marciano in the upcoming project, which is still looking for a director.

Marciano was a world-renowned boxer and heavyweight champ who held the title from 1952 to 1956, and remains the only boxer to retire undefeated in his class, carrying a record of 49-0. Undefeated: The Rocky Marciano Story will trace the boxer’s life from his early childhood to the plane crash that caused his untimely and tragic death in 1969 at the age of 45.

The boxer inspired the name and fighting style of Sylvester Stallone’s iconic character in the Rocky franchise, though Undefeated aims to be a more conventional biopic about the real life of the late fighter.

Renner can be seen next reprising his role as Hawkeye in Captain America: Civil War, and appears opposite Amy Adams in Denis Villeneuve’s upcoming sci-fi drama Story of Your Life.
