Yep, you heard that right - James and Lars are obviously just big softies...

Metallica are to provide voiceovers for a new animated DISNEY series, scheduled for early next year.

Frontman James Hetfield and drummer Lars Ulrich will supply the voices for a pair of teenage dragons in ‘Dave The Barbarian’.

The metal giants, who were recently forced to postpone dates on their world tour due to injury, will appear in an episode lasting 11 minutes. It will be shown on the Disney Channel in the New Year according to Yahoo.

As previously reported on NME.COM the band are scheduled to play two sold-out dates at London’s Earls Court on December 19 and 20.
