The Search for Weng Weng is a 2013 documentary film about Filipino actor Weng Weng (1957–1992), directed by Andrew Leavold. The film follows Leavold's quest to discover the story of the largely forgotten actor, whose real name was Ernesto de la Cruz. His starring roles were in locally produced action comedies films that found worldwide distribution in the early 1980s. Weng Weng is the shortest leading man in cinema history, standing at 83 cm. Leavold, who is Australian, decided to travel to the Philippines with a backpack and a camera and assemble every piece of information he could on the actor. Leavold interviewed many who sometimes both worked with and knew the actor. This includes Eddie Nicart, Bobby A. Suarez, Marrie Lee, Dolphy, Imelda Marcos, Tikoy Aguiluz, among many others. Leavold eventually discovered his remaining relatives, who described the actor's childhood and last years.

In 2007 a rough cut of the film was screened and caught the attention of producers who bought the project. It became the basis of Mark Hartley's Machete Maidens Unleashed! (2010), a documentary about cult films made in the Philippines, where Leavold worked as an associate producer and was credited for his original idea. Since it only mentioned Weng Weng briefly, it left Leavold unsatisfied who negotiated with the other producers so that he could finish his film. Leavold launched a successful Kickstarter campaign, and with a team he finished his film.

In 2013 the film premiered in the Philippines and played worldwide in the film festivals circuits the following year, being part of the official selection of the Cinemanila International film festival, Sheffield Doc/Fest, and Udine Far East Film Festival, also Leavold won the Melbourne Monster Fest. The film had a limited theatrical run in North America. It was well reviewed and considered to be insightful as it uncovers the life of Weng Weng while also providing a look at an obscure facet of Filipino culture.
