Peter and Jenna-Louise Coleman are currently in Australia as part of the Doctor Who World Tour, where they faced questions from fans as part of a Q&A event.
While he was keen to keep the details of the upcoming series of the show a secret, Peter happily revealed new information about what it was like taking over from Matt.
When the pair were on set together, Matt staged something of an unofficial handover, Peter explained, giving him a watch and stating: “The Tardis is yours.”
Peter also revealed how his Time Lord will differ from Matt’s, stating that his will be “slightly more impatient and extremely fierce”, reports The Metro.
"I don't feel elderly at all, and I don't think the Doctor's elderly, apart from the fact he's two and a half thousand years old.
"There's a magic about him which is not about being in your twenties and thirties.
"We don't consider the Wizard of Oz or Father Christmas to be too old. They're still magical characters, and the fact they've been around the block only adds to their magic."
‘Doctor Who’ returns to TV screens on 23 August.
