Samuel L. Jackson as Nick Fury
You might think that a movie starring Samuel L. Jackson isn’t a movie unless he’s dropped at least 500 F-bombs, but you’d be wrong. Samuel didn’t just tone down his language for his role of Nick Fury in the Avengers movie franchise, but he also kept it PG-13 as Mace Windu in the Star Wars movies.
The Director of S.H.I.E.L.D. made his first appearance in the first-ever MCU film—Iron Man—in the post-credits scene. He would also show up in the post-credits in 2011’s Thor before, in 2012, appearing on screen as the main character. While it appeared that his character was killed, he actually faked his death using Tetrodoxotin B.
