Tim Matheson + Suzanne Somers

It may have been for Somers but I am fairly certain Matheson had prior roles.

Matheson was in a few films as a teenager. Maybe even younger.

You DO know you can look up that very info on this website? Just click on his name in teh cast of this film and it takes you to his page and career.

It wasn't Matheson's first but it was Robert Urich's debut.

If American Graffiti was first that would have been Suzanne's first film (both are in 1973).
