I think that my parents used to watch the TV series "Callan", I can remember the title but would have been too young to have seen it at the time. I may or may not have watched some re-runs, I honestly don't know so I have treated the 1974 movie as my first Callan viewing. Brilliant actor Edward Woodward (who was so good in the 1973 classic "The Wicker Man") plays retired British secret agent Callan, lured back for an assassination job on a crooked German businessman. The two characters strike up quite a friendship with a mutual love of playing out historical battle scenes using model soldiers at the target's mansion, almost slightly surreal. Other interesting characters include a petty crook called Lonely on account that he doesn't wash so nobody wants to go near him (whoever thought of that name I salute you, brilliant!), a camp arms dealer known as The Greek and his henchman Arthur, played by the one and only David Prowse, a giant of a man probably best known for playing the physical part of Darth Vader. The movie packs in plenty of action - when Callan displays his martial arts skills the screen colour becomes tinted and goes into slow motion, pretty silly in my opinion, on the other hand there is a fantastic rural car chase, one of the movie's most memorable scenes. Woodward reminds me of Michael Caine, I could imagine him playing the part too. He also has a bit of Clint Eastwood's Dirty Harry Callahan, wise cracking on one hand, deadly serious on the other, in fact Callan's choice of weapon, a Magnum, is surely a nod to the American film. In addition to the plot, which isn't as straight forward for Callan as he'd hoped, we get a view of London in 1974, nice seeing the fashions, locations, old vehicles and a boozer (pub). One of my favourite lines has Lonely say "You're not going to shoot bears though are you Mr Callan?" after Callan, who bought the Magnum off Lonely, explains that it could blow a bear's head off. Callan is a tough cookie up against some very nasty people. It is violent at times but also amusing at others, I don't think that as a thriller that it was intended to be taken too seriously and is all the better for that.
