Two come along together for Gilliam
Gilliam has not directed a film since Fear And Loathing In Las Vegas in 1998, which starred Johnny Depp and Benicio Del Toro.
His two new offerings will feature at various film festivals across the globe.
Tideland, starring Jennifer Tilly and The Big Lebowski actor Jeff Bridges, will be screened at the Toronto international film festival and the San Sebastian film festival in Madrid.
Meanwhile, The Brothers Grimm will open in the US next week, while also being put forward for the Venice film festival next month.
It will star The Bourne Supremacy and Ocean's Twelve actor Matt Damon and Heath Ledger, the Australian who appeared in A Knight's Tale.
