Answer: Michael Schoeffling
The character of Jake Ryan in the film was portrayed by Michael Schoeffling, who went on to have a brief acting career after Sixteen Candles. Interestingly, Schoeffling almost didn't get the part of Jake Ryan - the producers thought he was too old for the role and initially passed on him. However, director John Hughes was adamant that Schoeffling was the right choice, and ultimately convinced the producers to cast him. After Sixteen Candles, Schoeffling continued to act in a few more movies, but eventually retired from acting in the early 1990s to become a carpenter. Despite only having a brief acting career, Schoeffling's portrayal of Jake Ryan remains a memorable and iconic character in the realm of 80s teen movies.
