A six-year-old girl's lemonade stand, raising money to find a cure for Angelman Syndrome, was visited by Suicide Squad stars Margot Robbie ('Harley Quinn') and Jai Courtney ('Captain Boomerang') on Sunday.

Na’Ama Uzan began selling lemonade a year and a half ago and has already raised $64K for the Foundation for Angelman Syndrome Therapeutics. She was inspired by her old brother, who is suffering from the "severe neurological disorder characterized by profound developmental delays, problems with motor coordination and balance, and epilepsy."

Robbie and Courtney caught wind of Uzan's inspirational story and decided to drop by her Toronto-based stand before heading to the Suicide Squad's wrap party.

"We heard about Na’Ama’s story and what she was doing for her brother Nadav and I just think it’s so inspiring," Courtney told CTV News. "It just shows that there’s there is no act too small when you are talking about making a difference."

Robbie told CTV, "I used to do old little stands like this when I was little and I’d just spend the profits on lollies at the corner store so I’m glad she is doing something far more noble with the cause."

Directed and written by David Ayer (Fury) and features an all-star cast: Will Smith, Margot Robbie, Jared Leto, Jai Courtney, Joel Kinnaman, Cara Delevingne, Viola Davis, Adewale Akinnuoye-Agbaje, Adam Beach, Jay Hernandez, and Karen Fukahara.
