Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
Steven Spielberg was strolling down the red carpet for the UK premiere of his film, War Horse.
Alongside him on the red carpet, was a big star of the film, a lovely horse!
He and the horse palled around in front of the cameras for a while, enjoying just hanging out on the carpet.
Even the Royals, Prince William and Kate Middleton were at the premiere.
They were there to see the horse, we assume.
