Science fiction and fantasy fans of all descriptions have arrived for this year's International Comic-Con in San Diego, California.
The convention is well under way, with discussion panels, photo opportunities and autograph signing sessions taking place. The biggest stars in television and film are attending the event, including Doctor Who actor Matt Smith and Kit Harington from HBO's fantasy epic Game of Thrones.
The cast and crew from The X-Files were also reunited on stage for a panel which included the show's stars Gillian Anderson, David Duchovny, who played FBI agents Dana Scully and Fox Mulder. Along with the pair, the panel featured writers and producers from the programme, who discussed the show's success and popularity 20 years after it first aired.
From its humble beginnings in 1970 the San Diego convention has now become a key date on the film and television calendar, with thousands of fans queuing up to meet their heroes.
