Long Shot movie billboards...

The odd couple trope is standard practice in comedy movies, but this weekend's Long Shot is the improbable duo of Seth Rogen and Charlize Theron.

He plays 'Fred Flarsky', a talented journalist and she plays 'Charlotte Field', the U.S. Secretary of State considering a presidential run, who just happens to be his former babysitter and his first crush.

Much to the annoyance of her advisors she hires him to be her speechwriter, and as they get reacquainted sparks begin to fly.

These joyful movie billboards were spotted along Melrose Avenue, Santa Monica Boulevard and Pico Boulevard from April 18 to April 23, 2019.

This outdoor ad campaign is like a breath of fresh air as it appears to feature stills from the movie and doesn't simply rely on the standard headshots of the stars to sell the comedy, plus they look like they have great fun and chemistry together.

Charlize Theron admirers can also check out these Mad Max: Fury Road billboards, these Dior perfume billboards and these billboards for The Huntsman movies.

Meanwhile Seth Rogen fans can enjoy these movie billboards for The Guilt Trip, these film billboards for The Interview and these billboards for the Neighbors movies.

It's likely and highly possible that this unusual pairing may be able to supply the laughter you're looking for at the cinema this weekend.
