The Sure Thing is a 1985 romantic comedy written by Steven L. Bloom and Jonathan Roberts and directed by Rob Reiner. The film stars John Cusack, Daphne Zuniga, and Viveca Lindfors; it introduces Nicollette Sheridan in the title role. The film chronicles the cross-country journey of college students Walter Gibson (Cusack) and Alison Bradbury (Zuniga) as they make their way from New England to Los Angeles, each in an effort to meet their ideal match.
The origins of the film came from an experience writer Steven L. Bloom had while attending Brown University. During this time, his best friend was attending Emory University in the south and was constantly recounting the good times he was having while absolutely nothing was going on for Bloom. Out of pity over his situation his friend arranged for him to meet a sure thing over spring break, so Bloom found a ride through a ride board and drove to Atlanta with a number of other students.
Film critic Roger Ebert praised the film and called it a "small miracle" for its handling of teenage material in an era when movies like Porky's were the norm. In a review for The New York Times, Janet Maslin wrote that The Sure Thing was "glowing proof of two things: Traditional romantic comedy can be adapted to suit the teen-age trade, and Mr. Reiner's contribution to This Is Spinal Tap was more than a matter of humor".
