When Fantastic Four: Rise of the Silver Surfer opens next week, it will introduce one of the most spaced-out creations in the comic-book pantheon, one famously immortalised by Quentin Tarantino in an exchange of dialogue blatantly shoehorned into Crimson Tide (1995) to give it pop-cultural kudos. Still can't quite place the Surfer? A lonely emissary of Galactus, Devourer of Worlds, he journeys the limitless void on an indestructible surfboard, readying planets for destruction, until the humble people of Earth tug at what's left of his silver heart.Like, wow. Cosmic, man. No prizes for guessing which decade the Silver Surfer was dreamt up in. The film won't be shown to the press until just before release, but regardless of its quality, it will prove two things: one, that no matter how many critics and even cinema-goers think a film is a dull dud, if it makes more than $300 million (£150 million) worldwide - as Fantastic Four(2005) did - it will have a sequel; two, that the current vogue for CGI-enhanced films made from comic books is far from burning itself out.
