The two were slated to begin filming the comedy Mail Order Groom, but the project has been pushed back.
The pair, who starred in the 2010 flick Date Night, is in the midst of juggling a packed schedule and won't be available to begin shooting Mail Order Groom next year.
Since the hit series 30 Rock ended its run earlier this year, Fey has focused her attention on film. The multi-talented actress can currently be seen opposite Paul Rudd and Lily Tomlin in the comedy Admission.
Next year, she’ll give us an extra reason to see The Muppets… Again!, which features Christoph Waltz and Ricky Gervais.
Fey will also star in This is Where I Leave You, alongside funnyman Jason Bateman.
Carell can currently be seen in the comedy The Incredible Burt Wonderstone, with Jim Carey and Steve Buscemi.
Later this year, Carell will take on films unlike his previous efforts including the Sundance Film Festival darling The Way, Way Back, a coming-of-age story with Sam Rockwell and Maya Rudolph.
The former Office star will also appear alongside Channing Tatum and Mark Ruffalo in the drama Foxcatcher. The film illustrates the true story of John de Pont, who suffered a schizophrenic attack and killed Olympic wrestler David Schultz.
Of course, his most anticipated upcoming project is Anchorman: The Legend Continues, which is set to hit theaters this December.
