Those checking out the film festival portion of Austin's South by Southwest will get plenty of Billie Joe Armstrong on the big screen. The Green Day frontman will appear in two separate movies, with 'Broadway Idiot' receiving its premiere during the event.

The Doug Hamilton-directed 'Broadway Idiot' focuses on Armstrong's involvement in the 'American Idiot' stage production, which actually starred the vocalist on select dates during its run. A trailer for 'Broadway Idiot' can be seen below.

The other Armstrong-starring flick is '¡Cuatro!,' which Green Day shot while they were recording their recent album trilogy. A highlights special aired on several cable networks in December, with the full film recently screening at the Aspen X Games as part of their film festival.

In addition to the two Green Day-related flicks, there are a number of other music acts featured in films screening at South by Southwest. Dave Grohl's 'Sound City' will air at the festival, coinciding with the singer's participation as the music portion of South by Southwest's keynote speaker.

Billboard also reports that 'Artifact,' a 30 Seconds to Mars documentary, will air during the film festival. The movie details the band's battle with their record label and the subsequent recording of their hit album, 'This Is War.' The movie was directed by Bartholomew Cubbins (aka singer Jared Leto). The festival will also feature movies centered on Bikini Kill singer Kathleen Hanna ('The Punk Singer') and a Snoop Dogg movie following his spirituality called 'Reincarnated.'
