Hot Pursuit is a disappointment. It’s not funny. Just minutes into the show, it becomes obvious that the film, which is essentially one extended chase scene, is going nowhere.

Policewoman Cooper (Reese Witherspoon) and drug lord wife Daniella Riva (Sofia Vergara) are travel mates in this would-be madcap comedy. Like last year’s Tammy, the set up is okay, the stars are likable, but the movie, ultimately, is a failure.

Cooper is assigned to escort Riva to Dallas where her drug lord husband is set to testify against a former partner. But the pickup is botched when gangs burst in with guns blazing. Cooper and Riva escape and take to the road in a classic Cadillac convertible, the first of several vehicles they’ll use to get to their destination.

Witherspoon, despite being raised in Nashville, speaks with a southern accent that sounds inauthentic. Vergara, brings little beyond her Modern Family TV persona to her role. Neither excels at physical comedy. Hot Pursuit is a mess.

Who gets the blame? Director Anne Fletcher delivered another bad road trip movie The Guilt Trip (with Seth Rogen and Barbra Streisand) in 2012. The writers David Feeney and John Quaintance are veterans of (mostly failed) TV sitcoms. With the exceptions of comedians Jim Gaffigan and Mike Birbiglia in small roles, the supporting cast has no real charm.

Witherspoon and Vergara have producer and executive producer credits, so they are among the culprits.

I’ll concede there are a handful of chuckles, but if you want big laughs you won’t find them here. (Even the outtakes that are shown during closing credits are not funny.) Do not pursue.
