Combining romantic elements with an enjoyable action movie is a tall order, but a few movies have managed to combine the two genres quite successfully in the past, Romancing the Stone and Mr. and Mrs. Smith immediately come to mind.
That which cannot be easily accomplished in a feature length motion picture can often work out just fine in a short film, for example this very entertaining rom-act-com called Epilogue, created by Dylan Allen for Amalgamated Picture Co.
It’s got the guns and the fun you come to expect from an action flick, and yet it manages to blend the romance into the story in an organic way that really makes you feel like you're watching the epilogue to an epic action movie.
