Honeymoon in Vegas
Do you know what a straight flush is? It's like... unbeatable.
Jack (Honeymoon in Vegas)
Jack loves his mom and wants to fulfill her commands. She wants him to get married, as "it is time." He meets Betsy. But she wants more than just being together. She wants commitment. And he decides to marry her.
The movie is so much fun, and different types of Elvises add even more fun. But the thing is that Jack has an itsy-bitsy problem called gambling. He lost a bit over $50,000 to a very rich man Tommy Corman (James Caan) in poker. But Tommy says that it is ok, if Jack "lends" his girlfriend for a couple of days.

Let's Go Back…
They were going to get married. That is why they went to Las Vegas. But they did even tie the knot, when Jack lost in the poker game. By the way Jack is played by Nickolas Cage, a marvelous actor. And Betsy is performed by Sarah Jessica Parker.
It is difficult to imagine how the girl would feel, if she was "lent" like that. So, she decides to take a chance. Tommy behaves like a real gentleman. He treats her like a queen. And he offers her to go to Hawaii. It is quite a nice place to go, isn't it?
So, they leave and Jack is freaking out, as his girlfriend left with Prince Charming. Not actually Prince but charming. And Jack wants to save their relationships. He rushes to Hawaii in search of the beloved lady.
Elvises
The guy, who was sitting next to Jack, when he lost the game, was singing just like Elvis. So nice and mellow. Then there were flying Elvises, who really made the movie even more interesting and hilarious. It is comedy, where Nickolas Cage plays kinda seriously but they manner adds only more fun.
Of course, if you are looking for the real romance with struggles, complicated with other circumstances, you should watch Casablanca or if you want more action and some killings and heroes, then it would be Casino Royale.
