I, Madman (1989)

[Trevor]

I saw this for the first time this weekend (on AMC) and I liked it, despite the fact that some of the FX were really clunky - that weird thing in the suitcase with the airholes, for example - but the makeup was great as was Jenny Wright's performance. 

I googled Randal William Cook afterwards and discovered that the dude has won three Oscars: wow.
