The Thought Bubble Festival is the UK’s largest event of its kind – an annual celebration of sequential art in all its forms, including everything from superhero comics to independent and small-press artists and writers.

Thought Bubble formed in 2007 as a non-profit-making organisation dedicated to promoting comics, graphic novels, and animation as an important national and international cultural art-form. Now in its 11th year, the festival has been extended over a full week with a jam-packed programme of events at a variety of venues across the city. Our aim is to cater to both long-time comic book fans and those who have never picked up a graphic novel before!

Previous year’s conventions have welcomed some of the biggest names in popular culture to Leeds including talented comics creators such as Mike Mignola (Hellboy), Ryan North (Squirrel Girl), Matt Fraction (Hawkeye), Kelly Sue DeConnick (Pretty Deadly), Geof Darrow (Shaolin Cowboy), David Aja (Immortal Iron Fist), Tim Sale (Batman), Adam Hughes (Wonder Woman) John Romita Jr (Kick Ass), Kate Beaton (Hark A Vagrant), Jason Aaron (Scalped), Alison Bechdel (Are You My Mother?), Mark Waid (Thrillbent), Frank Quitely (Batman & Robin), Charlie Adlard (The Walking Dead), Babs Tarr (Batgirl), Ben Templesmith (Thirty Days of Night), Adi Granov (Iron Man), Andy Diggle (The Losers), Mark Millar (Nemesis),  Tony Harris (Ex Machina), Becky Cloonan (Demo), Scott Snyder (American Vampire), Natasha Allegri (Adventure Time), Danielle Corsetto (Girls With Slingshots), Boulet (Dungeon), Tim Sale (The Long Halloween), Scott Snyder (American Vampire), Fiona Staples (Saga), Babs Tarr (Motor Crush) and many, many more. The convention represents a unique opportunity to meet the creators behind the comics!

2017’s festival programme will run from 18th – 24th September (with selected satellite and fringe events before and after these dates), and will include free art and writing based workshops for young people and adults, a two day academic conference plus talks and masterclasses led by industry professionals.

Our special two day convention includes an incredible line-up of leading artists and writers, and over 400 tables showcasing the best sequential art has to offer, with creator appearances, publisher presence, and retailers. The weekend will also feature portfolio viewings and competitions, as well as a huge cosplay parade. This promises to be one of the best events of its kind in the UK, as we enter our second decade of celebrating comics in style!




Thought Bubble started life in November 2007 as a one day event which took place in Leeds' Town Hall basement.

Since then it has gone from strength-to-strength, attracting attendees from around the world, growing to the current week-long festival format.


Thought Bubble is a not-for-profit organisation that seeks to promote literacy and artistic skills through the medium of sequential art.

We see graphical storytelling as an important cultural art-form, and believe it is the most stylistically and thematically diverse artistic medium in the world.
