Boyle native Chris O’Dowd has said that he is "enjoying" working on upcoming HBO comedy, Family Tree, as it is "totally improvised".

The show centres on a 30 year-old man called Tom Chadwick (O'Dowd), who embarks on a journey of self-discovery after his aunt leaves him a mysterious box in her will.

Speaking to Vulture, the 33-year-old actor discussed the free-form of the show, saying: "It's totally improvised: essentially, you go into each scene with a paragraph of story, but there's no dialogue written down. It's very exciting, but it's hard, I'm not gonna lie.

"It's a tricky skill to improvise while also getting all that story across, but I'm enjoying it. I have to say, I'm really excited for January because we're bringing in some of the guys who've been in his troupe for so long.

"It's been all English people up till now, but Fred Willard, Ed Begley Jr and Chris Guest himself come into the show in January, so I can't wait for that."

The BBC will broadcast Family Tree in the UK, while HBO is expected to air the series in the spring in the US.
