Brian Regan (born 2 October 1957 in Liverpool) is a British actor known for playing Terry Sullivan, one of the lead roles in the Channel 4 soap Brookside, during the 1980s and 1990s. He has also had small parts in other television series. On 12 April 2011, Regan was charged with the murder of a doorman in Liverpool and remanded in custody to await trial. He was cleared of the murder early the following year but was still imprisoned for nearly five years on a lesser charge.
He joined the cast of Brookside in 1982, first appearing in episode six. The character of Terry Sullivan was featured in some of the soap’s most dramatic storylines, and he was a regular mainstay of the soap until he finally left the series in February 1997. He had previously left the show for a short time to move to London, where he pursued his acting career, but later rejoined. According to an article in the Daily Mail in April 2011, Sullivan and his fellow Brookside character Barry Grant (played by Paul Usher) were the inspiration for comedian Harry Enfield’s Scousers.
