Leonard Maltin (b. December 18, 1950) is a famous movie critic, historian and also an author on several cinema-related books. He appeared in Gremlins 2: The New Batch as himself.
He was the host of his own show called 'The Movie Police' and was seen holding up a VHS copy of the first Gremlins movie, which he did not like and gave a bad review. While talking bad about the movie, a bunch of real gremlins shows up and attacks him, one even starting to choke him with a film strip, and he frantically changes his mind and shouts out that he was just kidding about bad reviews and now gives the movie a 'ten' instead... right before show switches to the test pattern (Gremlins 2 edition). It is unknown whether he survived the annihilation or died from choking.
