Having portrayed the Marvel Cinematic Universe's top-spy Nick Fury since the MCU's beginning in 2008's Iron Man, Samuel L. Jackson has developed a method acting habit whenever he prepares to reprise the role.

While promoting his return to the MCU in Captain Marvel, Jackson revealed in a print interview for SFX magazine that he has used one peculiar trick to get into character as he learns his learns that he's employed since 2011's Captain America: The First Avenger.

"I discovered on the first Captain America that I couldn’t learn lines with two eyes open and do them with one eye covered," Jackson explained. "So now when I’m actually doing Nick Fury I cover my left eye when I’m learning my lines, so I still have the full visualisation in my head. It’s a very weird thing but it works."

While Captain Marvel marks a younger Fury before he lost his eye, it remains an interesting trick the veteran actor has used to return to his MCU role for the past eight years.
