Pen-ek was selected to take part in the "Digital Short Films by Three Directors" project at the 2006 Jeonju International Film Festival. He directed a short called "Twelve Twenty", about a young man (Ananda Everingham) who falls in love with a woman he sees on the other side of an airport terminal, and then fantasizes about her throughout a 12-hour, 20-minute airline flight. Christopher Doyle provided cinematography and was also featured in the film as the pilot. The other filmmakers taking part in the project were Singapore's Eric Khoo and Darezhan Omirbayev from Khazakstan.
