"Life Is Cool" was one of four films produced by CJ Entertainment to receive investment from Keyeast, a media contents company co-established by actor Bae Yong-joon. Although actual shooting only lasted for one month, it then took almost two years and 140 artists to complete the rotoscoping, a technique in which animators traced over live action footage frame by frame. Visual effects were created by local production company DNA, who had previously worked on "The Animatrix".
