- Barry: "Hold on, mucker, you are gonna have to stop giving me a hard time."
- Phil: "No worries. You stop having me killed, and I'll stop complaining about it."
- ―Barry and Phil[src]
Barry was voiced by Timothy Spall.
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.
Events of Vice City Stories
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 she/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.)
- Coincidentally or not, the name of the character bears a bizarre resemblance to an Australian soccer player who played in Romania, Michael Thwaite. His last name is a combination of "Michael" and "Thwaite".
- 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.
