    We present a detailed discussion of the fundamental mechanisms for recently observed nonlinear electro-optical wave mixing effects in nematic liquid crystal films. Experimental results on photoconductivity, photorefractive-like two beam coupling, beam amplification, self-diffraction, and storage holographic grating formation in dye- and fullerene C60 and C61 doped nematic films are presented along with a review of two- and four-wave mixing theories. Nematic liquid crystal films are shown to be potentially useful for adaptive and optical storage applications
