Claire Foy Has a Case of the Giggles in 'The Girl in the Spider's Web' Blooper Reel (Exclusive)

ET is the only place you'll see the blooper reel for the latest 'Girl With the Dragon Tattoo' movie, on Blu-ray and DVD on Feb. 5.

More like The Girl With a Case of the Giggles.

Sure, that's a lot less intense than The Girl in the Spider's Web, but it was at least the case behind the scenes of the latest Girl With the Dragon Tattoo story. Just watch this exclusive gag reel, in which Lisbeth Salander herself, Claire Foy, can't keep a straight face as she shoots a bathtub scene, sings about windshield wipers and accidentally smacks a co-star for real during a fight scene.

The Girl in the Spider's Web, from director Fede Álvarez, arrives on Blu-ray and DVD on Tuesday with a slew of bonus materials, including making-of featurettes and eight deleted scenes, but only ET has the gag reel.
