The official trailer for Rules Don't Apply begins with Howard Hughes (Warren Beatty) insisting that if his plane doesn't fly, he will leave the country. We also meet an actress (Lily Collins) and her driver (Alden Ehrenreich). The driver has been instructed that if he makes a move on any actresses, he'll be fired.
As both actress and driver get to know one another, we see her playing piano and sing to him. She confesses that she's insecure about her appearance because she doesn't have "big bosoms" like other Hollywood girls. He responds by saying, "You're an exception, the rules don't apply to you." She later responds, "The rules don't apply to you either," and the two share a passionate kiss. All the while, the actress's song plays in the background and she sings, "The rules don't apply to you."
Things get even more tense when Howard Hughes shows an interest in her.
