Trailervision works on the principle that all those film trailers you fast-forward through on the Blockbuster video rental you argued over for 20 minutes are usually better than the movie itself. So instead, open your bottle of wine and settle back with www.trailervision.com – spoof trailers of movies which should but don't exist. Titles such as Harry Potter, Hidden Dragon; Charlton's Angels; and Mission Possible 3 show the small degree of topical references but mostly these one-minute trailers satirise the style, self-importance and smugness of Hollywood itself.

New items are added every week. Conveniently these can be viewed in a stunning choice of formats (well, three) – MPEG, QuickTime and Windows Media Player – and its flippin' well free!

Starting out as a TV special in Canada in 1999, the online version now includes collaborations with talents from around the world. It quickly became an Internet cult and now feeds back into TV – Channel 5 bought an initial 10 trailers last year. And like all the best comedy on the net, it's a short and simple, well-executed idea and updated regularly which means you want to come back for more.

And any site which includes a trailer for 'Hobbitt in the City' about 'the adventures of an urban Hobbitt who chances on the ring of power that gives its bearer the power to seduce beyond his wildest imaginings' has just GOT to be worth a minute of your time.
