A new comedy series in the works at Fox has made a casting change, scrapping the actor who played one of the three leads in the pilot, Deadline.com reports.

Jake Lacy, who starred with Becki Newton and Scott Foley in the pilot for "The Goodwin Games," has been replaced by actor-comedian T.J. Miller, the story reports.

The new show, from the creators of "How I Met Your Mother," follows three siblings who have to reunite and get along in order to receive the fortune left to them by their late father.

Foley and Newton are the older brother and sister, with Miller to play the little brother Jimmy. Miller’s character is described as “all heart, zero impulse control” and a perpetual screwup who has been in and out of jail.

Miller’s resume includes the movies "Cloverfield," "Our Idiot Brother" and "Yogi Bear." He also is the host of "Mash Up," a new stand-up series for Comedy Central. He reportedly impressed execs at both the Fox Network and 20th TV when he played one of the leads in the off-cycle sitcom pilot “Little Brother,” which didn’t get picked up to series.
