9-1-1 Spinoff: Liv Tyler to Star Opposite Rob Lowe

The 9-1-1 franchise is expanding.

FOX previously ordered a spinoff titled 9-1-1: Lonestar and the latest addition to the cast is Liv Tyler.

Deadline reports that the actress is playing chief paramedic Michelle Baker.

The character is described as “equal parts compassionate and ruthless," and those traits will come in handy when she goes up against Lowe's character.

Michelle is struggling with the past, two years after her younger sister Iris went missing.

According to Michelle’s official description, “she’ll stop at nothing to discover the truth — even if it means burning her own life down.”

Sounds like an intriguing character, right?

9-1-1: Lone Star follows a sophisticated New York cop (Lowe) who, along with his son, re-locates to Austin, and must try to balance saving those who are at their most vulnerable with solving the problems in his own life.

It comes from 9-1-1 co-creators Ryan Murphy, Brad Falchuk, and Tim Minear, so it's already poised to be another success story.

“The beauty of having a hit drama like 9-1-1 from the genius minds of Ryan Murphy, Brad Falchuk and Tim Minear is it allows you to explore thrilling stories as told through an array of distinctive characters,” said Michael Thorn, President of Entertainment, FOX Entertainment when the series was ordered.

“In 9-1-1: Lone Star, they’ve given us a special opportunity to expand the franchise into new territory – literally and figuratively -- and we’re thrilled to have the incomparable Rob Lowe headline this new iteration when it joins our schedule next season.”

Lowe added, “Ryan Murphy, Brad Falchuk and Tim Minear’s ability to make smart, unique, great television is unmatched. I’m elated to join this team.”

9-1-1 is entering its third season later this month, but the decision to craft a spinoff is unsurprising.
