''Incredible Invasion'' is one of four low-budget Mexican horror films Karloff made in a package deal with Mexican producer Luis Enrique Vergara. The others are ''Isle of the Snake People'', ''Fear Chamber'', and ''House of Evil''. Karloff's scenes for all four films were directed by Jack Hill in Los Angeles in the spring of 1968. The films were then completed in Mexico.<ref>Stephen Jacobs, ''Boris Karloff: More Than a Monster'', Tomahawk Press 2011 p 503</ref>

==Production== Karloff's advanced age was noticeable on the film; regarding his health status, Michael J. Weldon in ''The Encyclopedia of Film'' noted, "The ill, 81-year-old horror star is always shown sitting down or leaning against a support of some kind."<ref name="Pitts"/>
== Reception == AllMovie's synopsis of the film states, "The filmmakers barely had enough talent to adhere to the simplest of storylines, much less this hodgepodge of cut-rate H. G. Wells posturing and sleazy exploitation."<ref name="AllMovie"/> James O'Neil in ''Terror on Tape'' called ''The Incredible Invasion'' "one of the four awful low-budget U.S.-Mexican co-productions the great actor [Boris Karloff] filmed a few months prior to his death in 1969." Michael R. Pitts in ''Columbia Pictures Horror, Science Fiction and Fantasy Films, 1928–1982'' said that "While Karloff is quite good as the scientist and Christa Linder is strikingly beautiful as his niece, the overall production is labored", and that "[w]hile not as bad as ''Fear Chamber'' or ''House of Evil'', ''The Incredible Invasion'' must rank as one of Karloff's worst cinema outings."<ref name="Pitts">{{cite book |last1=Pitts |first1=Michael R. |title=Columbia Pictures Horror, Science Fiction and Fantasy Films, 1928–1982 |date=2014 |publisher=McFarland |isbn=9780786457663 |url=https://books.google.com/books?id=PKxN1as8XOMC&pg=PA112 |pages=112–113}}</ref>
