Zac Efron and Amber Heard are speeding up to star in thriller Autobahn.
The duo could be fighting over the driving seat after they have apparently signed up to star in the car chase movie by Welcome To The Punch director Eran Creevy, reported Deadline.
The former High School Musical star is tipped to play an American backpacker who gets involved with a ring of drug smugglers as a pick-up driver, but ends up being pursued by his employers across Munich's high-speed freeways. There's no word about Amber's character.
Autobahn, which has been co-written by Eran with F Scott Frazier, is revving up for a start date in the autumn in Germany.
Amber, who has been romantically linked to her Rum Diary co-star Johnny Depp, will next be seen in thrillers Machete Kills, Paranoia and Three Days To Kill.
