 The Cello Case Chase sequence down the snow took three days to  shoot. The cello was specially made of fibreglass, and fitted with  control handles on the sides and skis underneath. Firecrackers were  set in the snow to simulate gunfire and during filming the case  would tend to topple over as Timothy Dalton (qv) was heavier than  Maryam dAbo (qv). The exciting sequence was the brainchild of  director John Glen (II) (qv) who had to convince doubting  colleagues Richard Maibaum (qv), Michael G. Wilson (qv) and  Albert R. Broccoli (qv). He did this by hopping into an actual  orchestral cello case himself.
