Batman and Spider-Man mingled with Darth Vader and swordsmen from Game Of Thrones as Comic Con hit Belfast over the weekend.
Thousands of sci-fi fans, gamers, comic collectors, movie buffs and anime enthusiasts descended on the King's Hall for the first year of the convention.
Red Dwarf stars Chris Barrie, Robert Llewellyn and Hattie Hayridge – aka Rimmer, Kryten and Holly the Ship's Computer – signed autographs for delighted fans.
Organisers said the "fantastic turnout" meant the show will return next June. Managing director Bryan Cooney said: "Belfast has been a blast, the people are wonderful and we will definitely be back in 2015."
