Shane Richie has landed a new Saturday night BBC One game show testing contestants' reaction times and using high-tech slow-motion filming.
Each 45-minute programme will see families react more quickly as they are put through a series of tests which could range from being fired through the air to diving through glass panels.
At stake will be a £20,000 prize for the team which wins what programme-makers say are "a series of dynamic and extraordinary tests".
It is not known yet whether the six-part series will be screened later this year or next.
The show's creator Adam Adler from Objective Productions said: "We're creating a fun and entertaining test of human reaction times, covered by bespoke, state-of-the-art super slow-motion technology as well as new techniques which will allow viewers to see things never before captured in a game show."
The BBC's executive producer Karl Warner said "'Reflex' will be the fastest game show on TV, bringing together state of the art technology and brilliant game design that BBC1 families will hopefully enjoy."
'EastEnders' star Shane, 48, who plays Walford's Alfie Moon, has hosted a number of game shows in the past including 'Lucky Numbers' and 'Win, Lose Or Draw'.
He also presented a one-off edition of 'Jim'll Fix It' which the BBC screened as a tribute to Jimmy Savile in late 2011, many months before allegations emerged that the late presenter had sexually abused dozens of people.
