The film: P.S. I Love You (2007)

The star: Hilary Swank

The injury: You might think suspenders would be safe. But in the hands of Gerard Butler, they’re lethal weapons.

“His suspender clip had stretched about 10ft! The second I think it’s going to come off, it flies across the room and hits me in the forehead,” recalls Swank.

“I remember sitting there, just covering it and laughing and everybody’s standing around the bed. My make-up artist looked at it and made a face saying: ‘What are we going to do?’ I ended up getting stitches and I had a perfect suspender-clip mark on my forehead, with the little teeth in it.”

How could it have been avoided? Clothing goods company David Morgan sells Ergonomic Safety Suspenders with Velcro fastenings that should be a little safer.

“These suspenders are designed to take the load of a heavy work or tool belt off your hips. 2 inches wide, Super Tuff Stuff, 3 inch loops with Velcro closures to go over the belt. Recommended for police and others carrying equipment on leather belts, as well as for those using webbing belts.” Good for randy Spartans, too.
