If you're struggling to place Ellie Darcey-Alden here, she's the actor who played Harry Potter's mother Lily as a child during flashback scenes in the final film. Because of the limitations of such a role, she only made one appearance in the franchise, and is the youngest of the child stars featured on this list - not yet even 20 years old!
Darcey-Alden has been brought into showbiz the classic way, through dance and stage schools. Shortly after her Harry Potter appearance, she won a large role in a "Doctor Who" Christmas special, but in more recent years has taken a couple of steps away from acting. Dancing seems to bring her the most joy in life, and she competes all over the world as part of professional dance troupe. Her Instagram captures a young girl making her first steps into adulthood and finding her way in the world.
