A Hollywood stuntman will freefall almost 100ft live on air during a Channel 4 ad break.
Viewers will see Dave Grant jump without a harness, and at a speed of more than 50mph, at the site of a derelict flour mill, to mark the UK release of the new Michael Fassbender film Assassin’s Creed.
The action-adventure, also starring Marion Cotillard, sees Mr Fassbender’s character freefall dive from the top of tall structures.
Stuntman Dave will perform the stunt outdoors, in the dark, at Millennium Mills, in Newham, east London.
Hollywood star Michael said: “The action sequences in the movie are shot in an old-school fashion… in geographical locations with real people, with very little CGI or special effects.
“In the movie (stuntman) Damien Walters performed a record-breaking leap… from 120ft, unassisted by wires and ropes… I’m very excited.”
The 100-second ad will air on Sunday December 18, at around 9.10pm, in a break in Channel 4 drama Humans.
