Grand opera and grand humor, an Irish classic and a new Chinese-American comedy, one musical with dozens of hits and one with dozens of murders. It all figures into a wildly diverse season for live theater in Boston.

“The Ouroboros Trilogy”: Likely the most ambitious work to come to Boston this fall, this epic opera sequence is produced by Boston University alumna Beth Morrison, who’s been championing new music in New York for the past decade. The librettos were all written by another Bostonian, Cerise Lim Jacobs, who conceived the piece with her late husband, Charles. The individual operas — “Naga” (composed by Scott Wheeler), “Madame White Snake” (composed by Zhou Long) and “Gilgamesh” (composed by Paola Prestini) — incorporate Greek mythology to explore the themes of life, death and rebirth. The three operas will respectively be performed on Sept. 13, 14 and 15; and the entire 12-hour trilogy will be done tomorrow and Sept. 17. At the Emerson/Cutler Majestic Theatre, 219 Tremont St. Tickets: $10-$128, 617-824-8400 or artsemerson.org.

“Hamlet”: This Actors’ Shakespeare Project version of the classic aims to spotlight the universal truths in the Bard’s text. As director Doug Lockwood explains, his version uses the character’s family relations and his friendship with Horatio as the window into Hamlet’s soul. A key element is the choice of setting, the Church of the Covenant on Newbury Street, which will amplify the holy and ghostly strains of the plot. Emerson graduate Omar Robinson, who has numerous Shakespearean roles under his belt, plays the title role. Oct. 5 to Nov. 6 at Church of the Covenant, 67 Newbury St. Tickets: $30-$50, 866-811-4111 or actorsshakespeare­ project.org.

“The Plough & the Stars”: This Irish classic comes to Boston via the Abbey Theatre (Ireland’s National Theater at Dublin), which presented its premiere in 1926. The third play in Sean O’Casey’s “Dublin Trilogy,” it was originally set in the 1916 Easter Rising and addressed the impact of revolution on ordinary lives. Current director Sean Holmes updates the approach to explore the story’s contemporary parallels. Sept. 24 to Oct. 9 at American Repertory Theater’s Loeb Drama Center, 64 Brattle St., Cambridge. Tickets: $55-$95, 617-547-8300 or americanrepertorytheater.org.

“Jersey Boys”: Here’s an interesting thought: The Four Seasons’ original run of hits only lasted about 10 years (most of the ’60s, before their disco comeback). Yet the musical based on their career is well into its second decade — not to mention its third go-round for Boston — and still going strong, after a Clint Eastwood-directed film adaptation. Revisit the peaks and Vallis of the Seasons’ story when the musical returns to town this fall. Oct. 4-16 at Boston Opera House, 539 Washington St. Tickets: $40-$150, 866-523-7469 or boston.broadway.com.

“Tiger Style!”: Chinese-American playwright Mike Lew found that the trend toward hyper-strict “tiger parenting” was the perfect cue for a broad send-up, throwing cultural stereotypes into the bargain. The story hinges on a pair of siblings who find that their strict upbringing didn’t keep him from losing a job and her from getting a loser boyfriend, so they take their parental conflicts to the streets. Presented by Huntington Theatre Company. Oct. 14 to Nov. 13 at Boston Center for the Arts’ Calderwood Pavilion, 527 Tremont St. Tickets: $63-$85; 617-266-0800 or huntingtontheatre.org.

“A Gentleman’s Guide to Love and Murder”: This deliciously dark-humored musical (loosely based on the same book that inspired the 1949 movie “Kind Hearts & Coronets”) took Broadway by storm, winning the Tony for Best Musical in 2014. If you agree that marrying your cousin and poisoning your other relatives is the recipe for a jolly good time, catch the raucous show on its first national tour. Oct. 18-23 at the Shubert Theatre, 265 Tremont St. Tickets: $45-$125; 800-982-2787 or citicenter.org.

Mel Brooks: So you don’t believe Mel Brooks is a comic genius? Consider that just last week, he did a Q&A appearance in New York. One fan’s question was “Boxers or briefs?” and he shot back, “Depends.” Case closed. The writer/actor/director continues a freewheeling spoken tour. Oct. 22 at the Citi Wang Theatre, 270 Tremont St. Tickets: $78.75-$138.75; 617-482-9393 or ticketmaster.com.
