Michael Sheen is "fairly certain" he saw a UFO as a child.
The 'Good Omens' actor was told from a young age that his hometown of Port Talbot had attracted a number of alien sightings, and he told how he saw a "phalanx of light" when he was on his way home from school one day, but didn't tell anyone what he'd spotted until it had disappeared, so was met with disbelief.
