In this charmingly chaotic romantic comedy directed by Ben Palmer, thirty-four-year-old Nancy (played by Lake Bell) is navigating the treacherous waters of singledom, weighed down by her parents' constant nagging and a string of disappointing dates. After a disastrous evening, she impulsively picks up a self-help book titled "Man Up," only to find herself mistaken for a blind date by the charming and recently divorced Jack (played by Simon Pegg). Rather than correcting the mix-up, Nancy decides to embrace the lie, diving headfirst into a whirlwind night of unexpected connection and awkwardly hilarious encounters across London. As their chemistry grows, so does the pressure of her deception, especially when she discovers that Jack's ex-wife (played by Olivia Williams) and her own friends are closer to the truth than she realizes. With a sharp script from Tess Morris, the film balances genuine warmth with cringe-worthy comedy, exploring themes of self-acceptance and taking risks. Featuring a stellar supporting cast including Rory Kinnear and Sharon Horgan, this 88-minute ride is a witty and heartfelt exploration of whether a single, impulsive decision can lead to real love.
