Sci-Fi Festival

Superheroes and aliens, even the odd superheroine, have descended on London for the 12th annual Sci-Fi London festival of science fiction and fantasy films, which runs from 30 April until 6 May at the Stratford Picturehouse in East London (CLICK). On Sunday 5 May there will be free Doctor Who 50th Anniversary Celebrations Talks, with novelists and comic book writers and artists discussing the adventures of the Timelord, followed by a screening of Dr Who and the Daleks (1965) starring Peter Cushing. CLICK for a Telegraph slide show of fans parading in costumes of varying quality.
