Jared Gilman and Kara Hayward ("Moonrise Kingdom")

Why You May Know Them: It's unlikely you do. Wes Anderson's "Moonrise Kingdom" is the first role for either young actor.

What Cannes Could Mean For Them: The pair dually play the lead roles in "Kingdom," which finds them acting opposite Bill Murray, Tilda Swinton, Edward Norton, Bruce Willis and Frances McDormand as 12-year-olds who decide to run away into the wildnerness together. One of the most anticipated films of the festival (which it opens Wednesday night), if Gilman and Hayward hold their own against their respected co-stars, folks will take notice.

What's Next? Neither has lined up their second film yet.

Jessica Mauboy ("The Sapphires")

Why You May Know Her: If you pay attention to Australian pop culture, you may know the 22-year-old Indigenous R&B singer as the runner-up on the fourth season of Australian Idol and a subsequent pop star in her own right (she opened for Lady Gaga on the Australian leg of her last tour).  Additionally, she had a starring role in the 2009 film "Bran Nue Dae," which screened at the Toronto International Film Festival.

What Cannes Could Mean For Her: With a lead role in Wayne Blair's "The Sapphires" -- screening out of competition in the festival's main selection -- Mauboy could very well find fans outside of Australia. The film was picked up for American release by The Weinstein Company earlier today.

What's Next? Mauboy is currently focusing on her music career and is working on her third studio album.

Matthias Schoenaerts ("Rust & Bone")

Why You May Know Him: The 34-year-old Belgian actor had the lead role in last year's Oscar-nominated "Bullhead," which won him the Belgian equivalent of a best actor Oscar.

What Cannes Could Mean For Him: Playing the male lead opposite Marion Cotillard in Jacques Audiard's highly anticipated "Rust & Bone," Schoenaerts has a juicy role that could earn him considerable international attention.

What's Next? The actor has roles in two upcoming English language films, both of which could help him break in America.  The first actually sees him reprise his role from the 2008 Belgian film "Loft" in Erik Van Looy's English language remake (Van Looy also directed the original, though Schoenaerts is the only returning cast member). The second sees him re-team with Cotillard in Guillaume Canet's English language debut "Blood Ties," which also stars Mila Kunis, Zoe Saldana and Clive Owen.
