You'll never guess, but Cristiano Ronaldo's new, authorised biopic is something of a vanity project. Clearly a man who regards even brushing his teeth as nothing more or less than a chance to show off his perfect hair, sculpted bod and bulging (pay) packet was hardly going to submit to a warts-and-all documentary.And yet it is testament to the skill of the makers that, lurking at the edge of the frame, is an insightful and sad portrait of a yearning to fill a hole that can never be filled.That isn't to say that large chunks of it aren't filled with hootingly ludicrous self-regard.Whether counting his sports cars, showing off his underwear drawer of brightly coloured budgie smugglers, pouting when he loses a hand of cards or lovingly stroking his abs, there is no denying that, by any reasonable judgment, CR7 is an absolute weapon.In film terms, its 92 minutes is plenty.Cristiano and Cristiano Junior (of course) live this sort of sweet, sort of strange, bachelor boys existence in an impossibly gleaming man-pad, pa and son doing sit-ups together . Conspicuous by her absence is Junior's mother, a mystery figure whom Ronaldo vehemently refuses to identify.But the craving validation can be singing only one song and it is, of course, that old classic The Daddy Done Left Me.In CR7's case, this was a dad (dead in 2005) too drunk to have any relationship with. Ronaldo's brother, Hugo, inherited the old man's alcoholism.Their mum, Maria, looks to have had a hard life, telling tales of spousal abuse, as well as revealing a taste for sedatives. The family relies on Ronnie heavily, and not just for his money.Perhaps it's too glib to say an addiction to winning and polishing his legend (and pecs) are Ronaldo's compulsions, but a picture emerges of a driven, lonely, loyal and sympathetic figure striving to distract dad from the drink, but knowing it's too late.
