Ron Weasley's owl helped fundraisers make their charity event a success.
Billy, who played the Wesley's owl Errol in the Harry Potter films, joined in with a host of musical entertainment at the Schooner Inn in Albion Street, Southwick, on Sunday as they worked to raise money for Downs Syndrome.
Organiser Marshall Mahendran said: “It was sensational, absolutely sensational.
“All the acts were amazing and it was a great success.”
Musical acts included singers Driving Miss Debbie and Rockin Colin, cover band Happy Endings and drag artists Misty Lee and Triffari.
People also posed with Billy to have their photograph taken at the event, which raised £207 for charity.
