When Larry Hagman came back from acting purgatory to become a superstar as J.R. Ewing on "Dallas," most folks saw this as being a big step up from being on "I Dream of Jeanine." But Hagman's most pathetic moment really came with this 1972 film that he directed. "Beware! The Blob" (a.k.a. "Son of the Blob") is both a sequel to and a spoof of the 1958 Science Fiction Drive-In class "The Blob," starring Steve McQueen. He is long gone, and this time it is Robert Walker, Jr. (Charlie X on "Star Trek") who gets the responsibility of fight the big bad blob. The plot is essentially the same as the original. An unsuspecting guy brings back a sample of frozen goo from Alaska, where he was working on the pipeline. The goo thaws, starts with a fly, works through a cat, and then an entire family. The devouring is witnessed which means the heroine, Lisa (Gwynne Gilford) and her boyfriend, Bobby (Walker) spend time trying to convince the local sheriff that a giant red blob thing is eating people. Meanwhile the giant red blob thing is eating everybody, which pretty much means a complete cross-section of Seventies stereotypes.
Hagman must have called in a lot of I.O.U.'s because Burgess Meredith, Dick Van Patten, Godfrey Cambridge, and Shelly Berman all show up to be consumed by the red goo (watch for Hagman's cameo as a bum). If there was ever an attempt to actually make a serious horror film here, then it must have been abandoned early on in the production. Very few of the actors seem to be taking this thing seriously and Walker just does not have the heft to be the manly hero. As a horror film "Beware! The Blob" is not scary and as a spoof it is not funny beyond the sophomoric level of the decidedly lame. The death scenes are not particularly creative, although the special effects are really not that inept, but you get the feeling some of these victims are happily throwing themselves into the giant red blob thing.
