Some familiar faces will be featuring in ITV's revamp of Thunderbirds, albeit having undergone something of a revamp.

New pictures show how three favourites from the original series - Brains, Lady Penelope and her chauffer Parker - will look when Thunderbirds Are Go launches on ITV and CITV.

Parker's pink FAB1 car will also make a comeback, as will Sylvia Anderson - the voice of Penelope in the 1960s series - who returns as her great aunt Sylvia in an episode due to air later this year.

The series - co-produced by ITV Studios, Pukeko Pictures and Weta Workshop, will debut in Spring 2015.
