Back in the day (mainly the 70's) when Mann's had a sizeable slice of both domestic and international film work it would seem that another one of their contributions was 'The Boys from Brazil' (1978) starring Gregory Peck, Laurence Olivier and James Mason.
This was the craft used:
This was a Bell (as opposed to AgustaBell) but, aside from that one is at a loss to discover more because, as can been seen, the registration has been painted over. Why they didn't use the same colour as the remainder of the fuselage I don't know. Perhaps the director thought that a white regtangle would look smart!
Any offers as to when (one assumes 1977), where, the craft and driver?
It seems as though there may be need to compile an Alan Mann filmography!
