A BUDGET comedy-horror starring celebrities Keith Chegwin, Tony Blackburn and Russell Grant could make a killing at the box office after securing a nationwide release.

Kill Keith has been written and directed by Summertown-based film producer Andy Thompson.

Some scenes were shot on location, near Wantage, while other filming took place at Pinewood Studios in London.

The movie will be screened at the Vue Cinema in Grenoble Road, Oxford, from Friday, November 11.

Mr Thompson, whose son Cormac Thompson-Hale, 14, a pupil at Cheney School, has a walk-on part in the movie, said he was delighted the film, which cost more than £500,000 to make, would be shown in cinemas across the country.

He said: “I have worked as a producer on some films starring big names like Jean-Claude Van Damme or the Star Wars actor Mark Hamill, but this is the first I’ve written and directed myself.

“The film is coming out at just the right time in terms of how high-profile some of the celebrities in it are right now.

“At first, we thought the astrologer Russell Grant would be one of the lesser-known celebs in the cast, but everyone is talking about him because he is appearing in Strictly Come Dancing.

“The DJ Tony Blackburn is on Radio 2 and Keith Chegwin has a part in Ricky Gervais’s new TV show Life’s Too Short.

“My only regret is that Vanessa Feltz was never available — she was going to appear as a TV producer and be blown up, but in the end she could not make it so we just altered the plot a little bit.”

In the Shaun of the Dead-style gore fest, a breakfast TV show is seeking a presenter and everyone who comes forward to apply for the job dies a gruesome death.

In one scene, a man in a cellar watches old Swap Shop videos while surrounded by slabs of meat hanging from hooks.

It soon becomes clear that he is on a crusade to kill celebrities and the tension mounts as he moves closer to Mr Chegwin, who was a popular face in the late 1970s and early 1980s in the kids’ TV show Cheggers Plays Pop.

The presenter said: “I had a fantastic time making the movie and I can’t wait until it comes out.

“It is years since I have made a proper movie — I was Fleance in Roman Polanski’s Macbeth when I was a kid.

“But I have never laughed as much as when I read this script so I came over to Summertown to see Andy and we sat and discussed me getting a leading role.

“I’m pleased I got involved because the film has got a great reaction so far.

“I know it was supposed to be low-budget, but these films stilll cost a small fortune. In one scene there is a model of Tony Blackburn’s head and the prop cost £3,000 to make.”

The premiere is set to take place on Monday, November 7, at the Curzon Mayfair in London.

Mr Thompson and his son Cormac have appeared in the low-budget gore-fest The Scar Crow, which went on to be named Best Horror/Sci-Fi Film at the London Independent Film Festival in 2009.
