Freeman's last scripted TV comedy role was as a guest actor in Brian Pern. The actor, who plays Doctor Watson in Sherlock (pictured) and is now starring in Hollywood movie Black Panther, also appeared in Simon Amstell's online film Carnage last year.
Deadline reporter Peter White says: "A pilot for the show was recently filmed in London and I gather that both broadcasters are deciding whether to proceed to a full order. If commissioned, it would be the latest co-production between the two networks, which last teamed for Tom Hardy drama Taboo."
Further details about Breeders will be revealed if the show is commissioned.
