This Castrol double feature is produced by the master of rallysport films, Barrie Hinchliffe.

Hannu Mikkola, one of the world's greatest rally drivers, is featured competing in The Twilight Zone - 1982 Swedish Rally. 

The documentary includes dramatic in-car sequences of Mikkola hurling his Audi Quattro over the snow-covered Scandinavian roads during twilight races. 

Having dominated the event a tense climax is reached when both Hannu and team mate Michele Mouton fail to arrive on schedule, allowing Stig Blomqvist through to score a popular win in a third Quattro.

In Appointment at Penha, the giants of the world of international rallying meet to do battle in the Rallye de Portugal, the third round in the 1977 World Championship for Makes. 

Alen (Fiat), Waldegard (Ford) and Andersson (Toyota) engage in a three way struggle for honours over the mountains of northern Portugal. There is superb footage of on-the-limit cornering from the three teams.
