And then there was one… Bonnie Arnold (left) and Mireille Soria. Dreamworks Animation's Mireille Soria is stepping down from her role as co-president of feature animation and returning to producing. A veteran producer with over 30 years experience, Soria had been promoted co-president in January 2015 with Bonnie Arnold, following the departure of Bill Damaschke. The announcement about Soria was made in a December 12 memo by Universal Pictures chairman Donna Langley. In the letter, Langley confirmed that Arnold would remain in her role at Dreamworks, becoming the sole president of feature animation.
