(1976, Peter Ustinov, Helen Hayes)

Ralph Adams observes: “For this film there were 3 buses used. The one working on the roads was BK2136, a Dennis bus. It is now owned by Bicester Classics and I saw it today on a wedding party. The front bench is for the driver and 1 passenger, and there are 3 benches behind for 3 passengers each. There was a second bus which had a wooden radiator which was crashed into the Sentinel steam lorry. There was also a third bus used in the film (not sure why) but not in running order.” The PSV Circle's 'Preserved Buses' list has BK2136 as a 1922 Dennis 2-ton lorry chassis with a replica body:

Also seen briefly is NN373, a mock vintage bus built around 1963 by Smiths Coaches of Reading. The chassis is from a 1915 American Locomobile 45hp truck, the body came from a 1911 LGOC B-type bus:

NN373 also appeared in the TV series A Pin to See the Peepshow (1973)
