SPOILER: There is a scene after the closing credits: Smiler is stuck in the loser lounge, wearing braces and losing a game of cards.
Someone takes a picture of the Columbia Pictures logo on their cellphone and attaches an emoji to the Lady's head.
End credits are depicted as text bubbles, with an appropriate emoji for each position, i.e. a camera for the director and monkeys for the writers.
In the last few seconds of the opening credits showing the Columbia logo model a set of hands appear on the screen holding a smartphone and the person holding the smartphone changes the Columbia logo model's head to a smiley face with sunglasses.
