December is upon us, and that means holiday happenings all over the city. We've rounded up the best holiday concerts and shows so you can get into the spirit of the season. Not feeling all that Christmas-y, but still want to go out? A new musical with some major rock-star cred comes to Old City starting this month.

Or, if you prefer to plan, here are five of our favorite events happening in December.

FILM

"They Call Me Jeeg Robot"

Gabriele Mainetti's intriguing 2015 superhero movie mixes comic-book tropes with gritty cinematic neorealism in the story of a petty thief from the slums of Rome whose encounter with radioactive waste in the Tiber River gives him superstrength and near invulnerability. When a traumatized young woman mistakes him for the Japanese manga hero of the title, the alienated man turns from his criminal ways to protect her from a psychopathic gangster. - Michael Harrington

KIDS

"Pan"

There's plenty of sweet seasonal stuff to go around for the wee ones - here's something for the bigger children (say, 8 and older) who can handle a slightly darker scene. Joe Wright's 2015 action-fantasy film, packed with fights, explosions, and crocodiles, is a prequel to J.M. Barrie's classic tale, in which Peter and his friends Tinker Bell and Hook battle an evil pirate chewing up the scenery while singing Nirvana and Ramones tunes (yep, it's Hugh Jackman). - M.H.

11 a.m. Saturday, Bryn Mawr Film Institute, 824 W. Lancaster Ave., Bryn Mawr. $5; $4 ages 12 and younger. 610-527-9898.

Philadelphia Orchestra

Carl Orff's rhythmic powerhouse Carmina Burana has become one of the most popular works in the repertoire.

Daily Show correspondent Hasan Minhaj creates a theater piece about the "New Brown American" and about growing up first-generation Indian American, exploring issues of racism, family, and love. - Molly Eichel

The Carols

Through Dec. 31, Plays & Players, 1714 Delancey St. $28.

COMEDY

MUSIC

Iggy Azalea

She had two of the biggest hits of 2014 with her own "Fancy" and in a guest spot on Ariana Grande's smash "Problem." Since then, things haven't gone so well for the rapper from Mullimbimby, Australia, with the cancellation of an arena tour and growing consensus among rap fans that she's guilty of crimes of cultural appropriation. The road to redemption begins in Chester, apparently, where the Down Under emcee will headline with a free show at a relaunch of the venue the Block at Harrah's. - Dan DeLuca

8 p.m. Saturday, the Block at Harrah's Philadelphia Casino & Racetrack, 777 Harrah's Blvd., Chester. Free, 484-490-1800.

Norah Jones

She has come a long way since 2002's Come Away with Me, her celebrated debut. Jones is an eclectic, multifaceted artist who likes to warble a country tune (with the Willies), to rock out (with Billie Joe Armstrong), and to experiment with electronic textures (on the Danger Mouse-produced Little Broken Hearts). But she foregrounds the piano playing and jazz chops that made her famous on Day Breaks, her subtle and spacious new album, and with those songs at the heart of the set list, Friday's show at the Academy of Music should make for an elegant evening. - Steve Klinge

8 p.m. Friday, Academy of Music, 240 S. Broad St. $53.50-$77.50, 215-893-1999.

Steve Forbert

He has a lot more wonder than his one hit ("Romeo's Tune," the sound of 1980), and his live performances always show off Jackrabbit Slim's roots-rock chops and songwriting skills. - M.H.

8 p.m. Friday at Kennett Flash, 102 Sycamore Alley, Kennett Square. $22.50 to $30, 484-732-8295.

Lisa Fischer and Grand Baton

The renowned backup singer who has performed with the Rolling Stones (stealing the stage from Mick Jagger, no mean feat), Sting, and Tina Turner steps out front with her own band. - M.H.

8 p.m. Saturday, Bryn Mawr College's Goodhart Hall, 101 N. Merion Ave., Bryn Mawr. $20; $18 seniors; $10 students. 610-526-5210.

The new queen of Denmark always croons in dulcet old-world tones, yet this young, peroxided lass has enough sense of weird rhythm to sing out with Philadelphia expatriate Diplo's Major Lazer and its worldwide smash "Lean On." Now, the clarion-clear house-music vocalist is gearing up for her own hit-making barrage with cold cuts such as the finger-snapping "Final Song" and the thumpity-thumping "Drum." - A.D. Amorosi

8:30 p.m. Wednesday, Union Transfer, 1026 Spring Garden St. $22.
