David Duchovny was "nervous" about returning to directing.
The 56-year-old actor previously took the reins on episodes of his TV shows 'The X Files' and 'Bones' and was happy to get the chance to do so again for the second series of 'Aquarius', in which he plays homicide detective Sam Hodiak.
He said ahead of getting behind the camera: "I'm happy to have the opportunity, it's been a couple of years since I directed so I get a little nervous, It's been a while but I'm looking forward to getting my feet wet again."
And David thinks it is beneficial for the whole cast to have someone who knows the project as well as he does in the director's chair.
He explained: "We enjoy working with directors we've worked with before, we like getting into a groove with people we know, that's fun for the crew and everybody and it's the same when an actor does it because everybody knows how the show works, there's no breaking in period."
When it comes to getting into character, David - who has children Madelaine, 17, and Kyd, 14, with ex-wife Tea Leoni - truly feels like the detective once he's got his trademark spiky hair and is ready for filming.
Asked how he feels like Hodiak, he said: "It's always the hair, early on I made a decision it would be how it is.
"I come into work and look like myself then after sitting and getting my hair and make-up done I look like Hodiak, it's always about the hair."
ITV Studios Global Entertainment will release 'Aquarius' season two on DVD and digital download on November 28.
