Britt Robertson

Robertson began acting as a teenager in American television before building a growing film career through her twenties, gradually taking on larger and more prominent roles.

She played Casey Newton, the stubbornly optimistic teenager whose belief that the future is worth wanting drives Tomorrowland's entire plot. Already established in television with a growing film career, she carried a large share of the film's plot opposite George Clooney's more world-weary co-lead.

The role remains one of the largest of her career to date, and she has continued to work across film and television since.
