LEWISTON — The Public Theatre is requesting pictures and resumes from actors who would like to be considered for roles in the upcoming production of “Last Gas.”

Local auditions for Equity and non-Equity actors will be held in late July and early August by appointment only, and readings will be from the script. All roles are salaried.

Contract dates are Setp. 26 through Oct. 23.

“Last Gas” by John Cariani is about people from rural northern Maine. It’s a comedy, but the humor comes from the truth of who these people are.

Roles include:

* Nat Paradis — Nearly 41 but still somewhat boyish and unassuming, he is a wounded idealist. A likable and charming loser, he’s lived his entire life in a remote area of Northern Maine running a gas and convenience store with his father. He prefers to avoid conflict and does his best to appear “happy” or “fine” with his situation in life, but watching the Red Sox on TV is usually the highlight of his day. In his heart he is seeking a way to “get back to happy,” but change seems daunting.

* Troy Paradis-Pulcifer — Nat’s 16-year-old son is a perceptive and intelligent young man, with a healthy dose of wise-ass teenager. He is eager to get out of Maine and pursue his dream of becoming an astronaut. At heart he is a “good kid” who loves his dad. He also suspects he might have more strength and confidence than his dad does and he is growing a bit protective of his father.

* Dwight Paradis — Nat’s father, 63, is a charming, affable, larger-than-life kind of guy who can be a bit of a bulldozer when he wants to make something happen that he believes should be happening. He can be a bit inflexible and rough around the edges. He fancies himself a ladies man and pursues women too young for him with confidence. He loves a good time, but there remains a hole in his heart from when his wife left him. His son is a source of disappointment.

* Guy Gagnon — Nat’s best friend and sidekick is unemployed, overweight and loyal, with a wry and dry sense of humor. His love for Nat runs deep. He is more complex than he appears. A Zach Galifianakis type. He has a surprisingly graceful ability to swing dance.

* Tracy Pulcifer — Troy’s mother, 41, is stoic, opinionated and straightforward to the point of blunt. She is rigid, stubborn and overly literal. Possessing a dry wit, she is a substantial presence of a woman who enjoys wielding the power and status of being a forest ranger. She follows every “rule” in the book, and writes summonses to people when her life feels out of control and she needs to feel more powerful. Never the popular girl in high school, she’s had her heart broken and has learned to emotionally armor herself from having it happen again. She still loves Nat, but he doesn’t want her back.

* Lurene Legassey Soloway —  Nat’s former high school sweetheart who is now 40. Once the “golden girl” who left Maine to chase her dreams, today she returns home for the burial of her mother. Feeling lost, disillusioned and dissatisfied with the life she’s created in New York, she is desperately looking for something to give it more meaning. Perhaps reconnecting with Nat will be the missing piece? However, the stakes feel too high, and she sometimes tries too hard.
