Michael Arndt may be called into postapocalyptic America to rewrite Catching Fire, the next installment of The Hunger Games. Arndt won an Oscar for his Little Miss Sunshine screenplay and also wrote the surprisingly somber Toy Story 3. If a deal is completed, Ardnt would take over Simon Beaufoy's script and join director Francis Lawrence, who replaces Gary Ross. Lionsgate is aiming to begin production in late summer and on a tight schedule owing to Jennifer Lawrence's commitment to the X-Men: First Class sequel. She needs ample time to squeeze her that freaky Mystique suit.
