I’ve learned that NBC’s comedy pilot Fifth Wheel is not going forward, at least for now, after difficulties with casting. With the number of original scripted series on cable and digital platforms exploding, there were major concerns going into this broadcasting season that the depleted talent pool would put extra strain on casting, leading to a number of pilots folding over problems finding the right actors. So far, those concerns have not materialized, with Fifth Wheel the first pilot this season to be pushed. There will not be a noticeable void left as NBC already had ordered the most comedy pilots, 14, as well as two series, Tooken and Mr. Robinson, for next season. Fifth Wheel, from ABC Studios and the Mark Gordon Co., was written on spec by Heidi Niedermeyer & Elena Crevello. It an ensemble comedy of a tight-knit group of friends that centers around a young woman who confronts her new reality after her last single friend gets engaged. Gordon and Andrea Shay executive produce, with Niedermeyer and Crevello as supervising producers.
