19 Awesome Movie Cameos Nobody Saw Coming

15. David Hasselhoff - Guardians Of The Galaxy Vol. 2

After Ego the Living Planet (Kurt Russell) reveals his disturbing villainous plan to his son, Star-Lord (Chris Pratt), including the fact that he implanted the brain tumour that killed Peter's mother, he then transforms himself into David freaking Hasselhoff.

While in Hasselhoff form, he says. "I tried so hard to find the form that best suited you, and this is the thanks I get?"

It's a brief cameo that's ultimately pretty disposable, but the shock value makes it extremely entertaining all the same, not to mention the fact that Hasselhoff then went on to lend his voice to the "Guardians Inferno" song that plays over the film's end credits. Madness.
