To infinity, and beyond!

Sandra Bullock and son Louis took Halloween fun to new heights when they donned matching Toy Story costumes to go trick-or-treating in Toluca Lake, Calif., on Wednesday.

Wearing a red hat and a jumpsuit designed to look like jeans, chaps, and a Western-style shirt, the Academy Award winner, 48, channeled the Pixar classic's cowgirl Jessie, from Toy Story 2 and 3. Her son, Louis -- who will be 3 in January -- assumed the role of Buzz Lightyear.

The Extremely Loud and Incredibly Close actress adopted the too-cute tot in early 2010, the same year she divorced then-husband, Jesse James. The couple had planned to adopt Louis together, but James' affairs with multiple women led to Bullock filing for divorce and proceeding with the adoption process as a single parent. She's been a doting mom ever since.

"He's getting so big!" the star boasted earlier this year. Pointing to her hip, she added, "He comes up to here on me now!"
