In 1998, The Teenage Textbook was made into a film (The Teenage Textbook Movie) starring Melody Chen and Caleb Goh, which topped the box office in Singapore for four weeks. It was also made into a stage play by The Necessary Stage, starring Hossan Leong and Mark Richmond.
While at university, Tan represented NUS as a debater in international competitions and on televised debates in Singapore. More recently, he has appeared as a guest judge on the International Emmy Award-nominated debate TV show The Arena.
