You can read the What's On Stage review round up of Mojo here - most critics have given four or five stars - but what did the critics say our leading boys? It is Rupert and Ben that seem to garner the most comments:
"Daniel Mays and Rupert Grint are the jumpy, insecure sidekicks in the club, the first a non-stop jittery bugger with a hilarious line in feeble self-assertion, the other – in a more than competent stage debut – a moon-faced, slow-thinking foil who finds himself retching without any sick." What's on Stage
"Rupert Grint makes an assured stage debut as Sweets, a pill-popping, pill-dealing kid with a hollow confidence. His opening dialogue with Daniel Mays’s garrulous, sweaty Potts is played out at a beguilingly brisk comic pitch.." The Times
"Distancing himself from his alter-ego, Ron Weasley, the Harry Potter actor has chosen to make his stage debut, and a new start, with an edgy role.
It’s a formula tried and tested by his co-star Daniel Radcliffe, who went from heroic Harry to nude heart-throb when he starred in Equus in 2007.
Still, it’s a shock to see the loveable Ron as Sweets, a pill-popping member of London’s 50s underworld.
Almost as surprising is just how natural and convincing he is, showing great comic timing and delivery throughout." The Mirror
"Grint also shows his growing maturity as a performer as his much dimmer, but no less frightened, pal..." The Stage
"Colin Morgan is both wonderfully funny and desperately poignant as the club’s dim-witted cloakroom attendant." The Telegraph
"Morgan (spoiler alert) does one of the best death scenes I’ve ever seen." Daily Express
"Colin Morgan’s Skinny is a tragic, bullied study in human weakness, his final demise played with skill, precision and pathos." The Stage
"...there is a superb performance from Whishaw, who brings a drop-dead arrogance and a chilling touch of the psycho to the late club-owner’s abused son, Baby." The Telegraph
"Ben Whishaw as Baby radiates a toxic stillness, yet never lets you forget that the character is a victim of paternal abuse." The Guardian
"Whishaw is brilliant at creepy, capricious menace..." Daily Express
"Baby, played with dangerous psychotic charge by an utterly mesmerising Ben Whishaw." What's on Stage
"Oh yes. And Ben Whishaw (Q from Skyfall) as Ezra’s son, Baby, is the heart of it. He is sinewy, unnervingly still, angry, unpredictable. Cool to the point of crazy. He reacts to his father’s death with nagging chat about how Colin Morgan’s cadaverous Skinny has nicked his fashion sense. You dread what is really inside him.
Whishaw handles Baby’s dry wit — “There’s nothing like someone cutting your dad in two to clear your mind” — without resorting to off-the-peg psycho glibness. By the end, he is crying one second, bursting into song the next. It’s a performance far outside of his usual range, one that reminds us just how versatile an actor he is." The Times
"Ben Whishaw (once a pretty formidable Dane) offers up a Hamletesque portrait of Baby, savvy enough to play his new situation with an antic disposition but allowing the deep pain and fear to emerge subtly and incrementally. His father, we soon learn, sexually abused him, but this is a world that cannot afford any pity (his “type think the world owes them a trip to the zoo” as Potts puts it). Appropriately enough, Whishaw’s performance hovers perfectly between wounded vulnerability and a frankly disturbed menace that feels like his only recourse." The Stage
