Mad Dogs, Sky 1

Yes, the Sky 1 drama department is trying to elbow some room on the national sofa and their policy with Mad Dogs is to cast it to the very hilt. Thus John Simm, Philip Glenister, Max Beesley and Marc Warren, playing four old lags who’ve sort of lost touch over the years, board a plane for Spain, summoned for a nostalgic bunfight by another compadre.

The task of the first episode was to explain quite how they managed to get themselves into said pickle. It turned out their mucker (Ben Chaplin) was swimming in money, acquired by means which were not immediately apparent. This being the Costa (not sure which one), you kind of suspected the worst, but not the famous four, who lapped up the luxury of his show-home villa with its well-appointed facilities. “If you die before us”, said one of them out of the blue, “will you give us your villa?” With such a weighty Shakespearean portent clanking in the script like a funeral bell, you knew Chaplin wouldn’t be seeing out the episode .

When they found the corpse of a goat floating bloodily in the pool, the visitors may very well have smelt a rat, but no, they buried the body and went out on the lash. If I must think of something nice to say about this gradual accumulation of implausibilities, I'll pick on the well-observed awkwardness between the old chums, who didn’t quite know how to be around each other as they crumbled into middle age. But the script didn't have much time for the filigree nuances of male group dynamics. They realised something fishy was up when Chaplin took them out on a cruise in a gin palace stolen, he revealed, from the gentleman who dropped off the goat. Back home, their host then spent the evening abusing his chums for their various failings in life – divorce (Simm), professional deficiency (Glenister), alcoholism plus wife dead from suicide (Beesley) and something else for Warren, I forget what. All of a sudden they were rather keen to scarper, but their mobile phones were locked in a safe for 24 hours as part of a bet and then a dwarf walked in wearing a Tony Blair mask and shot their host through the head. (Do keep up.)

While no one will miss Chaplin’s exceptionally creepy and wholly unreal character in episodes two, three and four, it remains to be seen whether there’s anything else to come back for. It looks like it'll all get a bit Grand Guignol. But in the mean time Simm and Glenister are going very much against precedent, Beesley has barely been noticed so far and Warren, as is often the case, is playing a plonker. The coast of Spain is so far proving pleasant to look at and to keep it from looking like a holiday doco director Adrian Shergold shoots much of the action through the various camcorders. But you can play fantasy casting all you like; if the dialogue's pedestrian nobody goes far. When one of the boys loses some tennis balls, Chaplin replies, “One thing I’m not short of is balls.” Over on the posh channels, nobody talks like that. (The script is by Cris Cole.)
