Following months of rumors, The LA Times has finally confirmed that Zac Efron has signed on to play the titular role in the upcoming live-action version of popular ‘60s cartoon Jonny Quest.

The site also reports that Warner Bros. is considering changing the title to avoid comparisons with the flop Speed Racer.

The new adaptation is being scripted by Dan Mazeau. Race to Witch Mountain helmer Andy Fickman and actor Dwayne ‘The Rock’ Johnson were previously rumored to be attached.
