Alyas Batman en Robin

Alyas Batman en Robin (lit.  'Alias Batman and Robin' ) is a 1991 Filipino musical-comedy film which spoofs the titular superheroes from DC Comics, Batman and Robin. It stars Joey de Leon as Batman, Rene Requiestas as the Joker, Dawn Zulueta as Angelique Legarda, Vina Morales as Vina, de Leon's son Keempee as Robin, and Panchito as the Penguin. Several songs in the film use melodies taken from other pop songs such as "At the Hop", Bird Dog and "Surfin' Safari".[3]

Originally produced by Viva Films, the film was delayed from its original release in early 1989 when Warner Bros. objected to the use of their characters' names and costumes. The film was eventually produced and released on April 6, 1991, albeit by Viva Film's rival studio, Regal Films.

The film was initially an unauthorized production from Viva Films, set to be released in 1989[1][4] to capitalize on the then in-production 1989 Batman film starring Michael Keaton. Shooting lasted into June 1989, with comedians Joey de Leon and Rene Requiestas alleging that Dawn Zulueta was causing delays in the final weeks of shooting due to prioritizing her other commitments.[5] However, Warner Bros.[a] objected to the use of their characters' names and costumes, which resulted in production being halted a day before its completion.[6] Despite de Leon's attempt to remedy the situation by proposing to title the film Hello Batman... How's Robin, the release of the film was still blocked for some time.[6][7] The film was eventually produced and released by Regal Films in 1991, two years later than the intended 1989 release.

A sequel was planned, launching Thursday group member and popular matinee teen idol and heartthrob Hector Chua. However, those plans did not materialize.

The "R" on the Robin costume was intentionally stylized to resemble the logo of its eventual producer, Regal Films, a rival to the film's original production company Viva Films.

Panchito's Tiyo Paenguin literally means "Uncle Paenguin", which is a portmanteau of the names "Tiyo Paeng" and "Penguin". The name is also a double entendre of the Spanish term for fellatio.

Joey de Leon imitates the mannerisms of Fernando Poe Jr. in some scenes of the film. Ironically, Poe had earlier produced a similar spoof film of Batman in 1965.

Dawn Zulueta's character is based on Vicky Vale, Batman's love-interest who works as a reporter in the comics and as a photojournalist in Kim Basinger's version of the character in the 1989 film . Similarly, her name is a combination of the names of then-ABS-CBN News and Current Affairs correspondents, Angelique Lazo and Loren Legarda. Her butler, Noli Boy, on the other hand is a spoof of another ABS-CBN anchor Noli de Castro, with him often quoting the latter's signature Magandang Gabi, Bayan.
