When we paid a visit to the set of Mr Selfridge, our chat with leading man Jeremy Piven took a strange turn. Perhaps the party atmosphere of Rosalie’s wedding had gone to his head? Or maybe it was the sheer boredom of hanging around on set all day? Either way, he got one wacky documentary idea out of it.
Picture this: video cameras follow the actor into the real-life Selfridges on Oxford Street. He’s dressed in full period garb and starts ordering people around. “It would get a little crazy – that would be really fun to do.
“People would laugh at first, then I would keep going, then it would become awkward… and then you’d have to call the police. But then the police would think, ‘Ok, we have to take him in but what are the charges?’ You’d have to watch them try to process it.
“Then I’m in prison in my  gear. And then maybe there’s a gentleman there, his fetish is guys in period costumes, he takes a liking to me, it gets even weirder…”
At this point, we confess, we were rather confused. But Mr Piven was convinced of his bright idea: “Let’s pitch this!”
If he gets the go-ahead, we want a cut of his fee…
Mr Selfridge begins on Sunday 25th January at 9:00pm
