A new trailer of The Wedding Ringer, starring Kevin Hart and Josh Gad, has hit screens, Digital Spy said.

Gad plays Doug Harris, who has no best man for his fast-approaching wedding to fiancée Gretchen (Kaley Cuoco-Sweeting).

With that in mind, Doug decides to hire Best Man Inc CEO Jimmy Callahan (Hart) to be his confidant and provide him with groomsmen.

The group have one week to learn as much about Doug as possible in order to pass themselves off as his friends.

Doug is in danger of making Jimmy break his one rule - to never make friends with his clients.

The Wedding Ringer is released in the US on January 16, 2015 and in the UK on February 20, 2015.

A press junket for the film was recently scrapped in the wake of the Sony hacking scandal.
