It appears Diane Keaton won't be making her TV series debut this season.

According to Deadline Hollywood, HBO passed on its Keaton-starring comedy series, 'Tilda,' loosely based on Deadline blogger Nikki Finke. The show would've followed a powerful but reclusive writer but fell apart despite high-profile names like Keaton, director Bill Condon and producer Alan Poul aboard.

Ellen Page and Jason Patric were also booked to co-star.
