The actor Jordan Peele is best known for his comedy, or his impression of former President Barack Obama. That may change this weekend, based on early reviews of his inaugural film ― a fusion of comedy and horror set to debut in the U.S. on Friday. “Get Out,” a psychological thriller about racism written and directed by Peele, earned a coveted 100-percent score on the film review aggregation website Rotten Tomatoes. That means that all reviews for the film on the site so far ― 40, as of Wednesday evening ― are positive.
