Russell Crowe went looking for fruit bats - and stumbled on a "UFO".
The Les Miserables star released footage on YouTube of what he believes could be aliens outside his apartment in Sydney.
Crowe said he and a friend set up a camera focusing on the city's Royal Botanic Gardens but instead of fruit bats, their recording showed bright red lights flashing across the screen.
