The frosty world of Arendelle is set to expand as Disney CEO Bob Iger announces the development of Frozen 4, following the success of the first two films. While Frozen 3 is currently in production, the news of a fourth instalment was revealed during promotion for the "World of Frozen" expansion at Hong Kong Disneyland Resort. With Elsa and Anna’s saga becoming a top priority for Walt Disney Animation Studios, the announcement aligns with the studio's focus on sequels, including Toy Story 5 and a second Zootopia movie. Although release dates for these sequels are yet to be disclosed, the continued success of the Frozen franchise underscores Disney's pursuit of billion-dollar box office hits.
