The actress, who is currently promoting upcoming sci-fi movie Green Lantern, picked soaring across the sky as the ability she would like to have if she had a power ring as depicted in the comic adaptation.
But it might come as a surprise how Blake would use her powers if she was granted her wish.
“I can’t imagine anything more than wanting to fly,” she told Total Film. “And I could beat the traffic to get to Disneyland and get in for free!”
The Gossip Girl star also revealed what she likes about the film industry.
The 24-year-old gets a thrill from never knowing where her next project might take her or which role she will be playing.
“One of the things I love about films is the spontaneity,” she said.
