Top Gear host Matt LeBlanc has said he would like to return for another series of the motoring show but is not sure if he will.
His co-host Chris Evans quit the show after one series, saying he gave it his best shot but it was "not enough".
After he resigned, Chris said Matt was the "captain" that the show needs going forward.
Asked by television critics in Los Angeles if he would come back to the BBC programme, Matt said: "I don't know. I'd like to. There's nothing officially happening yet. Follow the BBC."
Radio 2 DJ Chris had previously said the motoring show and the former Friends star "were made for each other" and heaped praise on Matt for his dedication to the programme.
Chris described working on Top Gear as an "honour, privilege and a pleasure" and he had tried his best, but said his stint in the driving seat was "not meant to be".
The BBC has said it has no plans to replace Chris when Top Gear returned for a 24th season.
Facing questions from critics, Matt said his favourite part about appearing on the series was "probably the travel", adding that he visited places including South Africa, Morocco and Ireland.
He added: "That show has a pretty broad demographic. Everybody can relate to an automobile."
Matt was promoting his new show Man With A Plan on American network CBS, in which he plays a father who cares for his children after his wife takes a full-time job.
He said: "This is a new thing, a new character for me, a whole new side of me and I'm looking forward to it."
Matt added that his tenure on sitcom Friends made him critical of comedies, saying: "I'm a joke snob. I don't love what you call low-hanging fruit. I don't like that kind of stuff.
"I tend to go for a smarter joke, and if there's a discussion about a joke that not everyone will get it, that doesn't scare me away from the joke. I'd rather do jokes that take a little bit of thought."
