Is Kyle Richards An Uncredited Extra In Two Short Scenes?

Was Kyle Richards (of Halloween 1978, The Car 1977, etc. fame), an uncredited extra in two of the scenes of the MGM Midnite Movies DVD; "The Bat People" (1974) - (doubled with "The Beast Within" (1982))? The two scenes of who I think may be Kyle are the same - a tour group in underground caves being led and lectured by a tour guide - once near the beginning of the film, and once again near the end. Thx.
