Back to the Future's 25th anniversary reunion

Mind the plutonium … the bash kicked off, as all great birthday parties do, with a cake, this one in the shape of a DeLorean time machine, apparently after snow Photograph: Diane Bondareff/AP IMAGES FOR UNIVERSAL STUDIOS HOME ENTERTAINMENT Presents, too: the week before, Lloyd and Fox picked up a commemorative gong at the Scream awards in Los Angeles Photograph: Chris Pizzello/AP Christopher Lloyd (Doc Brown), Michael J Fox (Marty McFly), Lea Thompson (Lorraine Baines) and director Robert Zemeckis were all present and correct Photograph: Diane Bondareff/AP IMAGES FOR UNIVERSAL STUDIOS HOME ENTERTAINMENT Ditto Mary Steenburgen (right) who plays Clara Clayton in the third instalment Photograph: Charles Eshelman/FilmMagic Even Huey Lewis turned up (he wrote the theme tune and had a cameo as a teacher) Photograph: Charles Eshelman/FilmMagic The festivities have gone on a while. Here are Thompson, Lloyd, Steenburgen and Fox, alongside Zemeckis and Lewis earlier in the day Photograph: Richard Drew/AP And here they all are again, revealing their favourite lines from the series (Lloyd: 'Roads? Where we're going, we don't need roads') and what props they nicked from set (Thompson: the pink prom dress) Photograph: Diane Bondareff/AP IMAGES FOR UNVIERSAL STUDIOS HOME ENTERTAINMENT. More faces emerge, but there are still a couple missing Photograph: Diane Bondareff/AP IMAGES FOR UNIVERSAL STUDIOS HOME ENTERTAINMENT Awol No 1: Crispin Glover, who'd be unlikely to show, given his legal wranglings with the film-makers over unauthorised use of his image in the second instalment, which he declined to feature in Photograph: Ronald Grant Archive Awol No 2: Thomas F Wilson, aka Biff Tannen and all his genealogical iterations. This is much more surprising, especially given Wilson's apparent eagerness to remind people of his link with the films . Thompson, when quizzed, is reported to have said: 'He doesn't like to come out to these things. But he's great.' Is this the full story? Let us know , if you know Photograph: Ronald Grant Archive
