When Peter appeared on Top Gear in June 2008, he revealed he once left a Mercedes 300 CE Coupe (1966) in a St. John's Wood car park for two years while he was in the US. He now drives a Maseratti.
Other than Equus, Peter also starred in another Peter Shaffer play: Amadeus. But this time when it went to Hollywood, he did not recreate the role. It went instead to Tom Hulce.
(on Spooks)Peter: This show is not a documentary about the Security Services, it is entertainment so we have license to make it look as we imagine it might look.
(Talking about his character in "Spooks")Peter: Harry is a fun character to play. We don't have a lot of back story or character analysis in Spooks, it is plot driven and, as such, the story is really the important thing. I know a lot about Harry that the audience probably don't know. I like to try and give them a glimpse of that, even though it is not provided by the script.
(on the show "Spooks")Peter: There's no security in show business anyway and certainly no security in Spooks because you may not make it to the end of the episode. The first thing all the actors do is check the script, see if you make it to the end... you never know. It's a very good negotiating tool for the producers. (Laughs)
