During its eighth year, the festival will present more than 30 films.
The deal includes a proposed late-night FrightFest season on the Film4 channel as well as trailers on Channel 4's channels and online competitions.
'Film4 is pleased to be associated with this country's most well loved and respected premiere event for horror film fans, Katie Hayes, Marketing Manager Drama, Acquisitions and Film4, says. 'Film4's own horror film strand, Saturday Night Shocks, has been hugely successful and our association with Frightfest will allow us to schedule a complementary Frightfest season on the channel, taking this genre of film to an even wider audience. Our support of this festival also enables us to engage directly with the film community and continue to bring the Film4 brand to everyone with a passion for film.'
