Imagined cities and alien interventions will be among the fantastical themes of a four-day annual film event in Norwich in November.

Aurora, once known as an extravaganza of animation, is throwing off the label to "blur the boundaries between film festival and art show" at what will be the newly reopened Cinema City and other city venues.

Entitled Possible Worlds, the festival will include artist programmes, panel discussions, screen talks and special thematic film showings, as well as installation work, live performance and the best new films from across the world.

Cinema-goers can expect the fractured world of experimental filmmaker Robert Breer; the effervescent, celebratory explosions of colour in Jeff Scher's films; and the dreamlike and often disturbing interior by Naoyuki Tsuji.

This year's featured artists all present possible worlds and environments shaped by experience and emotion rather than physical phenomena alone.

A series of panel events will look at the possible worlds the manipulated moving image creates, under the titles Interior Worlds, Layered Worlds, Interactive Worlds and Immersive Worlds and featuring a rare opportunity to meet Robert Breer.

Also appearing are filmmakers Marjut Rimminen, Naoyuki Tsuji and Jim Trainor, theorists David Surman, Barry Atkins and Tanya Krzywinska, artist Bruno Martelli and artist collective Semiconductor, who will also perform at the festival. Other events include thematic film programmes by international guest programmes, installation work by photographer and video artist Axel Antas, filmmaker Yuiko Matsuyama, software artist-collective Igloo and a new commission by sculptor CJ Mahony. Aurora comes to Cinema City from November 7 to 10.
