Sonic the Hedgehog makes a surprise appearance in the second trailer for The Angry Birds Movie 3, which arrives December 23, 2026.

The Angry Birds Movie 3 centers on Red, voiced by Jason Sudeikis, balancing fatherhood of three children with saving his island from extinction. The film's ensemble cast includes Josh Gad, Emma Myers, Rachel Bloom, Walker Scobell, Danny McBride, Keke Palmer, and Lily James, among others. John Rice directs, with The Angry Birds Movie 2 filmmaker serving as screenwriter.

Paramount's Sonic franchise has grossed over $1 billion across three films since 2020, with Ben Schwartz voicing Sonic and Jim Carrey as Dr. Robotnik. A fourth Sonic installment is scheduled for March 19, 2027. The Angry Birds crossover marks the first major announcement for either franchise before next year.
