Don't Tell Her It's Me Movie (1990) Trailer - Plot Synopsis: Gus Kubicek (played by Guttenberg) is a depressed and overweight cartoonist who recently won a battle against Hodgkin's disease.
His caring sister Lizzie Potts (Long), a nosy romance novelist, responds to his sadness by trying to set him up with a suitable woman.
Yet to do so she must make him seem more dynamic and attractive.
When Gus falls in love with Emily Pear (Gertz), he adopts the persona of Lobo Marunga, a leather-clad biker from New Zealand.
Emily ends up falling for Lobo but Gus tries to tell Emily the truth as he ends up in bed with her.
The next day Lobo tells Emily that he's Gus and she gets furious with him and tells him to get out.
Gus, hurt, supposedly goes away to New York when in fact he is going to a friend's wedding.
The movie ends with Emily tracking down Gus at the airport and they share a kiss as Lizzie watches through binoculars.
