Dolan's special guests perform stunts and hold their nerve during hidden camera set-ups in the presence of celebrities or the British public.

[1] Before its first broadcast, Balls of Steel received publicity during the London premiere of the film War of the Worlds when actor Tom Cruise was squirted with a water pistol disguised as a microphone as a part of Olivia Lee's Prank TV segment.

[4] Sveriges Television, where the Swedish version Ballar av stål was going to air, decided to cancel the show after massive criticism.

[6] Balls of Steel responded to OFCOM saying that the vomit used by the Annoying Devil was fake and a disclaimer was added when the episode was repeated.

A further complaint to OFCOM was not upheld when the show explained that the "victims" in Neg Dupree's Big Stranger Rodeo Urban Sports segment had been "set up".
