Samuel L. Jackson has ''no issues'' with his stuntman getting injured on set.

The 65-year-old star - who admitted to using a body double ''extensively'' for his role as Nick Fury in 'Captain America: The Winter Solider' - isn't worried about his stand-in's welfare, claiming it's part of his job to get hurt.

Speaking to BANG Showbiz at a press conference for the new blockbuster at London's Dorchester hotel, he said: ''I use my stunt man extensively I have no issues with him being hurt that's what he's paid to do.

''He loves it, he's from a stunt family, his father was a stunt man, all of his brothers are stunt men. Before they eat breakfast in the morning their dad kicked them down the stairs, or made them jump out of the window to come down to get their breakfast. So I used Kianti [Elam], God, he worked more than l do sometimes.

''It's way better to see him. You stand there, they throw a punch, you duck out of the way, they fight, you get up and go 'urgh', that's it. Believe me, it's good for you.''

The 'Unbreakable' actor even tried to encourage his co-star Scarlett Johansson - who is expecting her first child with her husband Romain Dauriac - to use a double more when filming the action-packed scenes left her ''limping.''

She asked the BAFTA-winning actor: ''Why didn't I learn that from you. After so many movies, every time I come in limping, Sam's like, 'Why don't you let people who are better do that job.' ''

Despite suffering from minor injuries on set, Scarlett, 29, insists she'd rather do her own stunts and face the consequences.

She said: ''I like to be able to do as much of the stunt work as possible and you take a little bit of a risk with that, but I'd rather that than have to hand off my scenes to the stunt team. As amazing as they are, all the time, I'd rather do some of it and have some battle wounds that way I can compare bruises.''
