"And I'm like, am I gonna get haunted by the ghost of Harrison Ford one day when he dies if I play...?"
The 43-year-old star was referring to a 2019 interview with Ford where he suggested nobody could replace him as Indiana, reports aceshowbiz.com.
The 80-year-old star said at the time, "Don't you get it? I'm Indiana Jones. When I'm gone, he's gone. It's easy."
Ford is returning as Indy for the new flick, which sees James Mangold take over behind the camera from Steven Spielberg, his co-star Antonio Banderas says it was "so unbelievable" seeing the film icon in character.
The actor recalled, "The first day I arrived, I was in the makeup trailer, and I turned around and there he was in the full Indiana costume with the hat and the whip. Phoebe Waller-Bridge was there with him, too, and it was so cool."
He added, "I still remember the first time I saw 'Indiana Jones' in a theatre and the crowd was crazy about it. I thought, 'This is like going back to the old adventure (movies) in a completely different way'."
