Following on from our report late last year on the Crash the Super Bowl advertisement competition, Melbourne filmmaker Peter Carstairs has made it to the 10th and final round with his hilarious entry Ultrasound.

Carstairs has a one-in-three chance to be aired during the Super Bowl, win $1 million USD and receive the opportunity to collaborate with renowned director Zack Snyder while working with Warner Bros. Pictures and DC Entertainment.

Now, he needs our support to become the first ever international entry to take the grand prize winner, so vote for his video at crashthesuperbowl.doritos.com. Voting closes January 31st.
