Appearing on "The Drew Barrymore Show," Gerard Butler discussed an array of his movies which included "P.S. I Love You." When the subject of "P.S. I Love You" came up, Butler explained that he absolutely loved working with Hilary Swank and that the role helped him get out of his actor's mind. He then joked that he loved Hilary so much that he accidentally almost killed her. Butler then elaborated and brought up the scene in the aforementioned film when his character was dancing around in his underwear and boxer shorts and said that this had gone on for at least a day and a half.

Butler then spoke about how dangerous his suspenders were during this particular scene and said that they kept getting caught on things because of the crocodile-style attachments, adding that the cameras had plastic shields on them for protection. Butler then said, "I'm crawling towards the bed; it gets stuck, it released. Boom! Flies over my head, hits her in the head, and slashes her head. I mean, I cut her up — you could even see the teeth. She has to get taken to hospital. Literally imagine this studio, and in three seconds, everybody's gone and I'm just sitting there in my Irish tummy box of shorts and my boots and a pair of socks and I just started crying. I was like she's off to the hospital; there's nobody on set." Luckily, this wasn't a serious injury, though this behind-the-scenes story will surely give fans of "P.S. I Love You" a different perspective of that famous suspenders scene.
