Churchill's early work included stints on Supergirl,[1] Uncanny X-Men as well as the Deadpool: Sins of the Past limited series, in addition to a lengthy stay on Cable, the latter gaining him (along with writer Jeph Loeb) fan acclaim.
The title, inked by Mark Farmer, saw a change in his usual drawing style, the result of a shoulder injury which required surgery.
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 Churchill 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,[3] Doug Braithwaite, Olivier Coipel, Duncan Fegredo, Simon Furman, David Lafuente, John McCrea, Sean Phillips and Liam Sharp,[4] 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 November 23, 2011, with all royalties being donated to Yorkhill Children's Foundation.
