Jimmy Kimmel and Oscars celebrities surprise strangers in the cinema

Getting to see an advanced screening of a film is already pretty cool, but it's even better when the film gets introduced by Jimmy Kimmel and Gal Gadot.

And it's better still when a bunch of other celebrities -- from Lupita Nyong'o to Mark Hamill -- show up to give you free snacks, and the you suddenly realise you're actually live on the Oscars.

One lucky man with a glorious beard even got to introduce the next presenters.
