(CNN) It was Isabella Tadlock's dream to be able to bend her fingers and pick things up. But she was born with a disability that made that challenging.

So when the 11-year-old "Star Wars" fan asked for an R2-D2 bionic arm, she thought it was going to be the best gift ever. Then came the call from someone familiar.

Mark Hamill, who played Luke Skywalker in the movie series, had a video call with Isabella when he found out her new arm had been delivered. She showed him her new R2-D2 arm and after the two had a 30-minute conversation, he sent her passes to Disney World.

"He could not have been more encouraging and kind," Isabella's mother, Pamela Tadlock, told CNN.
