STARS of Star Trek, Doctor Who and Game of Thrones are among the special guests due to attend the UK's longest running not-for-profit science fiction convention, which takes place in Southampton in early February.

The Sci-Fi Ball celebrates its 22nd year at the Grand Harbour Hotel from February 5 to 7 with a three day itinerary of unique events for the whole family to enjoy.

The star-studded line-up of science fiction and fantasy stars will be helping to raise much-needed funds for the Teenage Cancer Trust.

Casey Biggs who will be attending the entire weekend as well as performing as part of a special Star Trek cabaret told Your Entertainment: “Star Trek: Deep Space Nine is still so strong in the minds of Star Trek fans that it's always rewarding to be able to meet and chat about the magical world of Star Trek.”
