Return to the Blue Lagoon
(1991)

Lili (Milla Jovovich) refuses to join the ship crew, and convinces Richard (Brian Krause) not to return to civilization, but instead stay in the island, so they can raise their child there, where -according to Lili- "there's no evil, no lies and no guns".  He agrees.
