Barry Mickelthwaite is Phil Collins' manager in Grand Theft Auto: Vice City Stories. It is implied in one mission that he had a sexual experience with Reni in Monaco after becoming heavily inebriated with champagne. He also owes money to Giorgio Forelli, which puts Phil's life in danger. Barry has an accent which suggests he is from Birmingham, UK. As far as managers go, he is of poor quality, putting Phil's life on the line just so he doesn't end up with a concrete overcoat. Phil is very fortunate to have Victor become his personal bodyguard as Vic manages to save Phil many times throughout his stay in Vice City. After Reni's fourth sex change s/he tells Barry he should have breast implants and after the mission "In the Air Tonight", Phil goes on to say Barry should have taken Reni's advice: they'd look great with the pair he's using for his head. (This is after Phil's third time almost getting popped.)
According to an in game dialogue between Barry and Phil Collins, before Barry became Phil's manager, Barry used to manage a talking dog called Puddles.
Mickelthwaite could also be based off of Barry Taylor, another character portrayed by Timothy Spall in the English drama 'Auf Wiedersehen, Pet'. Along with the same actor, they share the same first name and the Birmingham accent.
