The actor felt it would be appropriate for his character, `evil ex` Gideon Graves to steal his girlfriend Ramona Flowers` pants and even wore the perfume of Mary Elizabeth Winstead - who plays his on screen lover - every day. He is quoted by website Movie Retriever.com as saying: "I came up with this idea, mostly out of fear, that my character, Gideon Graves, by the time we meet him, he has Ramona Flowers back. I had this idea that my character flew from New York to Toronto with like just a carry-on bag and he didn`t wear any underwear because he rarely wears underwear. "They spent the night together and the next morning because she`s his again and he wants ownership - he thinks in that way - he would have worn her underwear; to own her; to have her underwear on him. And I also wore her perfume every day. "I asked the costume department to go find me some red silk panties. I came into my dressing room and there were 20 different pairs - silk, mesh, silk-mesh. Every day while I was working and while you watch Gideon Graves, he`s wearing Ramona Flowers` panties." Jason insists he is prepared to do whatever it takes to get into character in his films. He added: "I`ve never been formally trained as an actor. For that reason, I don`t really have one technique that`s the exact same every time. So, I just kind of do the best I can. It`s sort of like learning a new city. Every time it`s just different."
