I really liked this movie, but it does have some things about it that need to be put to rest before you judge it. First of all...
lt is a low quality film by many mainstream standards. lt has a lot of lame acting. The storyline is not totally coherent and/or consistent. lt is overall, a corny, 70s horror movie about Satanic greater magic rituals. So bear all of that in mind, mentally prepare to appreciate that kind of movie, and allow yourself to be entertained by it. Here's where l'll explain the reasons l love it:
Devil's Rain has some really great actors in it. William Shatner and Tom Skerritt play frontline roles as, you might traditionally say, the 'good guys.' Their characters represent stereotypical, morally lukewarm Christians, at odds in the movie with a cult. This cult, headquartered in a desert ghost town, is led by Jonathan Corbis, played amazingly by Ernest Borgnine. His character Corbis, furiously devoted to Satanic worship, has time travelled by way of black magic as a demon shapeshifter to pursue the Preston family, them being descendants of the 17th century pilgrim group that delivered Corbis to witch hunters.
As if to give more hardcore fans a little easter egg they'd have to look for, Anton LaVey is very briefly in the film as a priest in Corbis' rituals. Also making a random appearance is a young John Travolta. Both of these men have hyper brief roles and barely utter 3 lines between them. Hands down though, the scenes with Borgnine playing the most unexpectedly convincing role of a deathly passionate sorcerer, absolutely make the movie. His voice, his evil looking eyebrows, the striking red robes he wears, his over-the-top yet perfectly executed lines... This is gold, really. In a super obscure movie like this, too.
lf you like old horror movies, 70s horror movies, movies about devil worship, etc, any or all of the above... watch this dam movie. Hell, buy it, it's like less than $10, used. Borgnine's acting is incredible, grisly gore effects cap off the ending, the occult rituals and imagery are authentically enacted, and you have the mega flavour that comes with this type of low budget, high enjoyability film. Devil's Rain is a gem, and an absolute must-have for obscure movie fans and occult aficionados.
