(2001, Mary-Kate Olsen, Ashley Olsen)

Risible vehicle for the Olsen twins has a group of American students with their high school Model United Nations team, visiting London and doing touristy things. There are a couple of musical gems: they visit a disco where the dancers are incongruously swaying sedately to Plastic Bertrand's punk pogo classic 'Ca Plane Pour Moi; later they recreate the Beatles' Abbey Road album cover to a soundtrack of Depeche Mode's 'Just Can't Get Enough'. A still of a London Routemaster appears in the opening credits, and several Routemasters, a First Dennis Trident and an Original London Sightseeing Tour Metrobus are glimpsed, but the killer scene comes when the students spy an RML class long Routemaster with a flake grey stripe pulling in at a bus stop on route 94. They scramble across the road and climb on - by which time it's mysteriously turned into a standard-length RM with cream stripe and gold fleetname on route 36! Footage follows of the kids sightseeing from the upper deck. The whole sequence is shot blurred-style presumably to indicate the kids' excitement at being in London-England, so the following ids are speculative, but the RML appears to be London United RML2463 (JJD463D):

The RM appears to be Marshall-refurbished London Central RM1280 (280CLT):

Also glimpsed out of the window of whichever Routemaster is used for the internal shots is this Volvo B12/Van Hool of Bakers Dolphin of Weston super Mare:

Later in the film the students arrive at a country house on Collins Coaches J710CWT, a Volvo B10M/Plaxton new to Wallace Arnold (thanks Graeme Selway for the id):
