On 9 April 2011 Phillips was one of 62 comics creators who appeared at the IGN stage at the Kapow! convention in London to set two Guinness World Records, the Fastest Production of a Comic Book, and Most Contributors to a Comic Book. With Guinness officials on hand to monitor their progress, writer Mark Millar began work at 9am scripting a 20-page black and white Superior comic book, with Phillips and the other artists appearing on stage throughout the day to work on the pencils, inks, and lettering, including Dave Gibbons, Frank Quitely, John Romita Jr., Jock, Doug Braithwaite, Ian Churchill, Olivier Coipel, Duncan Fegredo, Simon Furman, David Lafuente, John McCrea, and Liam Sharp, who all drew a panel each, with regular Superior artist Leinil Yu creating the book’s front cover. The book was completed in 11 hours, 19 minutes, and 38 seconds, and was published through Icon on 23 November 2011, with all royalties being donated to Yorkhill Children’s Foundation.
