Russell T Davies and Julie Gardner, the producers who brought Doctor Who back to life, have been sending BBC Radio Wales' Jamie and Louise show "postcards" tracking their new life and adventures in Los Angeles.
In this latest edition they're joined by David Tennant and Torchwood director Euros Lyn, who were flown out to to take part in the San Diego Comic Conference.
Tennant, who is about to end his tenure as the Doctor, said he was greeted by a 7ft Scooby Doo as he arrived at the conference, which Davies describes as a "geek's paradise".
The Jamie and Louise show is on BBC Radio Wales on weekdays from 9am to noon.
