With a voice that can shift from a Valley Girl squeal to a mother's stern whisper, she's become Hollywood's secret weapon for scene-stealing character work.
Alanna Ubach's career is a masterclass in memorable supporting roles, built on a chameleonic voice and fearless comedic timing. She broke through in the 1990s with sharp turns in cult films like 'The Brady Bunch Movie' and 'Sister Act 2: Back in the Habit.' Her performance as the endlessly upbeat, legally clueless Serena McGuire in 'Legally Blonde' cemented her status as a comedy fixture. Ubach has since navigated a vast range, from the hyper-realistic waitress in 'Waiting...' to the stern but loving spectral matriarch Mamá Imelda in Pixar's 'Coco.' Her work on shows like 'Euphoria' demonstrates a darker, dramatic edge, proving her talent extends far beyond the laugh line.
1965–1980
The latchkey kids. Raised during divorce, recession, and the end of the Cold War. Skeptical, self-reliant, media-literate. They invented indie culture, grunge, and the early internet — then watched the Boomers take credit.
Alanna was born in 1975, placing them squarely in the Generation X. The events that shaped this generation — economic uncertainty, the end of the Cold War, and the rise of personal computing — shaped the world they entered and the choices available to them.
