Oliver Chamberlain
Background
Oliver "Ollie", "O-Man" Chamberlain co-manages a boutique estate agency in North London. His friends called him O-Man due to a birthmark on his head which looked like the number 6. He is originally from Newton Haven. Oliver's sister is Sam Chamberlain.
During the events of The World's End (2013) played by Luke Bromley and Martin Freeman
Gary King goes to a house Oliver is selling and tells him of the plan to complete the Golden Mile. Young Lady and Young Man are taking a tour of the house and tell Oliver the house is out of their price range and Gary ruins the deal for Oliver. Before agreeing to go attempt the Golden Mile again, Oliver reconfirms that Andy Knightley is going and Gary tells him, he is. On Friday Peter Page, Oliver and Steven Prince meet at the train station, including Andy. Gary picks them up in the Beast, the same car he had when they were young and as they are driving into town, Gary is pulled over by a Motorcycle Policeman. He tells the Motorcycle Policeman he left his driver's license at the gym and tells him, his name is Peter Page and as the Motorcycle Policeman is checking on the information, tells Peter the Beast is still registered to him. They stop at a bed and breakfast and B & B Landlady checks them in. As they are walking, they pass Greg, Seb, Luke, Tyler and Sam.
They enter The First Post and Publican 1 fails to recognize them, but gets them four beers and a water for Andy. They go to The Old Familiar, which has the same look and layout as The First Post. Publican 2 also fails to recognize Gary or the others. Peter asks Gary about his mother's funeral and Oliver calls Sam and invites her to come and visit with them. Sam stops by and leaves. They pass by a large statue on their way to The Famous Cock. At The Famous Cock they see Basil and call out to him right before they are kicked out by Publican 3 for Gary being banned years ago. At The Cross Hands, they see the "Marmalade Sandwich" sitting in a booth. Shane Hawkins asks to borrow an empty chair and Peter feels sad that after all the years of Shane picking on him, he didn't even recognize him. Andy gets in an argument with Gary and Gary walks off to go to the restroom, leaving his phone on the table. The phone rings and Andy picks it up and sees Gary has lied and his mom is calling him.
Andy and the others burst into the restroom and see Greg's body which appears to be robotic. The other members of Greg's group enter the restroom and a fight breaks out between them and Gary and his friends. Gary and his friends win and try to use their cell phones, but the lines won't connect. Gary figures out that all the townspeople have been replaced. They go back to their table and Andy chugs five shots. The Motorcycle Policeman sees them and asks them how they are doing. Gary thinks they should continue with the Golden Mile so the town doesn't suspect they know what is going on and Andy agrees. They go to The Good Companions and order drinks from Publican 5 and then on to The Trusty Servant where Oliver makes a brief stop in the restroom and is turned into a Blank.
Later, after The Network leaves and the world collapses, Oliver Blank continues as a real estate agent.
