'Sharp Objects' star Amy Adams and director Jean-Marc Vallée talk family dysfunction and rock to Led Zeppelin

BEVERLY HILLS, Calif. - Get actress Amy Adams and director Jean-Marc Vallee into a room together and at some point Led Zeppelin might start blaring through the puny speakers of an iPhone, with Adams doing a subtle sing-along midway.

"We could keep this going," Adams warns, as she bobs her head in time along with Vallee to the iconic band's "What Is and What Should Never Be" inside a Beverly Hills hotel on a recent afternoon.

The musical moment is enough to make you wonder what could have been. The two were set to team on a biopic of Janis Joplin, with Adams, a multi-Oscar nominee whose work in films such as "Arrival," "American Hustle," "Nocturnal Animals" and "The Master" propelled her to the top ranks of Hollywood actresses, set to play the '60s rock singer.

That project was ultimately shelved. But music, ever so slightly, has finally united them in a different endeavor: HBO's "Sharp Objects."

Making its premiere July 8, the limited series is an adaption of the 2006 debut novel of the same name from author Gillian Flynn,
