The Monty Python films have been voted best TV series to be made into a film by Radio Times readers.
The Monty Python team were a hit on TV and film
The films - including The Meaning of Life, The Life of Brian and The Holy Grail - beat Mission: Impossible and Star Trek to top the poll.
But Thunderbirds and the recent release of Dukes of Hazzard, were voted among the worst TV spin-offs.
More than 8,000 Radio Times readers placed their vote to mark the launch of the Radio Times Guide to Films 2006.
TOP FIVE FILMS
1. Monty Python films (1975 onwards - including The Meaning of Life, The Life of Brian and The Holy Grail)
2. Mission: Impossible (1996)
3. Star Trek films (1979 onwards)
4. The Fugitive (1993)
5. Batman (1966)
A 1977 version of Are You Being Served, was named worst TV spin-off, followed by The Avengers, starring Uma Thurman and Ralph Fiennes.
Barry Norman, who wrote the introduction to the guide, said: "Most movie spin-offs from TV series are doomed to failure because each episode of a series is simply an anecdote.
"A movie should at least be a short novel - and you can't make a novel out of an anecdote."
Other films included in the "best film" category were: The Untouchables (1987); The Addams Family (1991); The X-Files (1998); South Park (1999); and Starsky and Hutch (2004).
Films in the "worst category" included: Sgt Bilko (1996), Scooby-Doo (2002); Charlie's Angels (2000); The Saint (1997); and Bewitched (2005).
