The 'Enter Sandman' musician is promoting the band's new 3D concert film, 'Through the Never', at the Cannes film festival in France, where he revealed his ambitions to move into the director's chair himself one day.
He told Getty Images Entertainment: ''The biggest enemy I have is time. Metallica in its 32nd year is busier and has more projects on the table and takes up more of my time than it ever has.
''I may do it. I would love to do something. I have actually been offered the chance to both direct and produce as well as write and I've acted in a couple of films, so I do what I can.''
Lars admits making 'Through the Never' was ''overwhelming'' for the band, especially as they are used to having so much control over everything when they are in the studio.
He added: ''Making a movie at this level has been a little overwhelming. In the music world you get very used to controlling your environment and in the film world there is nothing to control. It's just like a complete clusterf**k. And there's a bizarre beauty in that.''
