Russell Crowe tweeted a link to a video on Wednesday (March 6th) that he claims to be a UFO flying by a camera he set up to capture fruit bats at the Sydney Botanic Gardens. The 23-second video shows a disk-like object flying from the right side of the frame to the left.

Many people were quick to try and disprove Russell’s claims by blaming it on lens flare or other issues with the camera but the actor followed up with another tweet saying, “Canon 5D, No Flash, can’t be a lense flare because it moves , camera is fixed” Other skeptics of the extraterrestrial sighting are mocking Crowe by asking for his dealer’s number.

• Russell happens to be portraying an alien in an upcoming film. He plays Superman’s biological father from Krypton, Jor-El, in Man of Steel.
