HBO's acclaimed limited series "Sharp Objects" may turn out not to be so limited after all.

Showrunner Marti Noxon is hinting that the miniseries based on Gillian Flynn's novel could return for a second season. If it did, it would follow in the footsteps of network sister "Big Little Lies," which was also based on a book without a sequel and intended to be a one-off.

During a keynote address at SXSW, Noxon noted that "Sharp Objects" didn't delve into many aspects of the life of protagaonist Camille (Amy Adams).

"Maybe there will be a sequel and we'll get to find out," she said. "Gillian [Flynn] and I have some thoughts on it."

Noxon also mentioned that she had initially envisioned "Sharp Objects" as an ongoing series that focused not just on Camille but on the people of the town Wind Gap.

Even if HBO wanted a second season, getting the team back together again — particularly Adams and Golden Globe winner Patricia Clarkson — could prove to be a tough endeavor.

Noxon herself told The Hollywood Reporter last August, after the finale, that it would be near impossible. "It's off the table in terms of, people are going on to their next projects, and it was a pretty hard A-team to assemble," she said.

"It's not hard to imagine from a story standpoint, because obviously we love these characters, but from a technical standpoint it seems like a long shot."

Of course, getting the cast of "Big Little Lies" together for a second season seemed impossible, too. But it happened (AND they got Meryl Streep to join them).

Still, even if Noxon thinks there's more story to tell, she also feels that "there are certain things that are just limited, and should be."
