What would you do if Daniel Radcliffe unexpectedly showed up to an event you were attending? Those who attended a screening of his film What If were treated with just that and proved to be overcome with joy.

During quick interviews after the film to give their thoughts on what they just watched, Radcliffe surprised unsuspecting fans and their reactions were priceless.

In a video posted by BuzzFeed, Radcliffe reveals himself as fans are sharing their thoughts on the film, and fortunately for him, they were all raving reviews.

His fans’ reviews of the film were opposite from his own review of his performance in Harry Potter and the Half-Blood Prince.

He recently opened up about his performance in it, admitting it “wasn't my favorite installment overall. I just hated my performance.”

He added, “The film was good, but it's a huge amount of exposition. I think it's the most beautiful of all the chapters ... but [it's] basically about setting up No. 7. I just wasn't very happy with No. 6 in terms of my own performance."
