Chris Evans has said there was an "apocalyptic" atmosphere at Top Gear as he arrived to take over. The presenter said it was like "Armageddon" in the office after the sacking of Jeremy Clarkson last March.
Clarkson's departure from the BBC TV motoring show, after he threw a punch at a producer, was followed by that of co-hosts Richard Hammond and James May, plus several senior staff.
When Evans arrived as the new host, only one "lone warrior" - producer Alex Renton, on the programme since 2004 - remained, he told the Television Critics' Association in Pasadena, California.
Rebuilding the show, and learning the skills needed to lead it, has been a "baptism of fire", the 49-year-old added. The BBC recently dismissed as "nonsense" a tabloid claim that Evans was struggling to master talking to a camera while driving at high speed.
