THE HEAT (15) Pavilion, Galashiels

What looks at first like a female remake of 48 Hrs turns out to be that rare event in Odd Couple action pictures, a Triple C jackpot – character, chemistry, charisma.

Pairing Sandra Bullock, as an ambitious, uptight, control-freakish FBI agent, with Melissa McCarthy – the rude one from Bridesmaids – as a fat, foul-mouthed, undercover Boston cop, was a light bulb moment in the history of casting.

How could they tell whether it would work as well as this? Jason Bateman and McCarthy in Identity Thief pales into insignificance by comparison.

The plot, concerning the usual suspects (drug baron, serial killer, police mole) is less important than how these women spark off each other.

McCarthy dresses like a bag lady and swears like a trooper.

Her presence dominates because her character is out there, bold as brass knuckles, and Bullock plays catch up admirably.

The ultimate bonding sesh in a back street bar is inappropriate hilarity at its drunken best.

The heat is on. Feel the fire.
