Christopher Mintz-Plasse says his 'Kick-Ass 2' bondage costume is a ''pain in the ass'' to wear.

The 24-year-old actor - who plays Chris D'Amico / The Mother F***er in the comic book action franchise - found his S&M uniform uncomfortable to film in, but joked his fellow cast members must have enjoyed watching him donning the unusual garment.

He said: ''Everyone else got a kick out of watching me! It looks hilarious, twisted and dark but it was a pain in the ass to wear. Literally.''

While Christopher found his outfit uncomfortable to wear during filming, he got off much more lightly than co-star Chloe Moretz's teenage stunt double, who cracked her head open while shooting the motion picture.

He added to Nuts magazine: ''Chloe Moretz's character's stunt double was thrown into a wall by The Motherf***er's henchwoman, Mother Russia, and she cracked her head open.

''She's only like 13 or 14, but she's OK now.''
