“Game of Thrones” is back on April 6th for its fourth season, same night as the premiere of my favorite show, “Veep,” both on HBO. Last night spent the big bucks on “Game of Thrones” with a truly lavish premiere at Lincoln Center and in Avery Fisher Hall. They hired the New York Philharmonic orchestra to come on stage and play the series’ theme music and some of its score before Episode 1 was screened. The show’s composer, Ramin Djawadi, got to conduct. This is a big deal.

The screening was followed by a swanky dinner at the American Museum of Natural History, under the suspended whale. Some of the guests included director Joel Coen with his Oscar winning wife Frances McDormand, and son Pedro; double Oscar winner Sally Field accompanied actor Charles Dance, who stars in “Game of Thones, plus Oscar winning writer director Terry George (“Hotel Rwanda”) was there along with many members of the huge cast including Emilia Clarke, Peter Dinklage,  a tattooed Lena Headey, and British superstar veteran actress Diana Rigg, aka Emma Peel from every boy’s fantasy circa 1966 in the real “Avengers.” One of our favorite young actors, Evan Jongkeit, came with girlfriend Zosia Mamet from “Girls.”

HBO dressed up the Lincoln Center plaza with white tents for the red carpet, and a large menacing looking dragon. Dragons are very big in “Game of Thrones.” As the ever cute, adorable Emilia Clarke explained, “My character gave birth to them, now they live under her bed. It’s a long story.” Emilia is filming the new “Terminator” movie during her break before returning to “Thrones” in July.

What happens in “Game of Thrones”? A lot of people get stabbed to death and there will be blood. Definitely a lot of blood. A lot of threats are made. Peter Dinklage, who plays Tyrion Lannister, manages to meet every challenge despite the odds of annihilation by several terrible means. Peter has come a long way since his big 2003 debut in “The Station Agent.” He’s the linchpin in this group of medieval maniacs.

I ran into Amanda Peet. Her husband, David Benioff, is one of the creators of “Game of Thrones.” Amanda, always in demand as an actress, just had a great run with her first play “The Commons of Pensacola” here in New York. She told me she’s working on a new one and she, at least, a native New Yorker, was sympathetic to my complaints about drivers in Los Angeles. Next time, I’m hiring one of those flying dragons to take me around!

PS Tonight don’t forget to check out HBO’s terrific “Doll & Em.” I forgot to mention this, but some of Episode 6 takes place in the famed J.Sheeky restaurant in London. The restaurant’s equally famed front of house guy, John Andrews, has a speaking part. He’s terrific!

HBO keeps looking for a half hour hit with grand gestures. Will “Sex and the City” or “Entourage” ever be replicated? “Veep” is the nearest thing they have to that kind of perfection.

On Wednesday, the cable network will debut a show they didn’t make, brought in from Sky TV in London but set mostly in Hollywood. The six episode series is called “Doll & Em,” produced by actor Alessandro Nivola, co-written by and co-starring his actress wife Emily Mortimer with her childhood best friend Dolly Wells. It falls like a blessing from the sky.

The premise is that the fictional Emily and Dolly are also best friends. Like real life Mortimer, Em is a British successful actress living in New York. Just as she goes to Hollywood to make a movie, Em’s best friend Dolly breaks up with her boyfriend in London. So Em invites Doll to come with her and be her assistant.

“Doll & Em” is a comedy, but it’s also quite dark and gets quite dramatic in places. There are plenty of knowing laughs, too, about the inside workings of Hollywood and of the actors’ life. But it’s more grounded than just that as Dolly starts to become Emily. It’s “All About Eve” with a major twist. It’s also very subtly and skillfully textured. The women are best friends. But there are complicated layers to the friendship. Those layers are peeled back very cleverly by Mortimer and Wells. We watched the six episodes back to back last night at a screening. But it will be worth the wait to go week by week, believe me.

We know Emily Mortimer from Woody Allen’s “Match Point” and Aaron Sorkin’s “The Newsroom” among other projects. Wells is known in London but this will bring her to a new audience. They are smart, funny, attractive. You start out thinking this is an update on “Absolutely Fabulous” but then you realize– everyone is sober, and serious.”Doll & Em”  is all about nuance.

Frankly, the people involved could have made “Doll &Em” as a two hour indie film, gone to Sundance, etc and it would have been a big hit. It’s that good. But it is episodic. Scruffy New York native Azazel Jacobs, who wrote the scripts with Mortimer and Wells, told me: “I felt freed from having to make transitions that would have been forced.” He definitely sees the potential for a second six episode series. Viewers will want it, too.

Last night’s screening brought a very cool crowd: Maggie Gyllenhaal and Peter Sarsgaard, Mark Ruffalo, and Mykhail Baryshnikov were among the guests. Oscar Isaac arrived, having just wrapped — literally Sunday night– J.C. Chandor’s new film with Chastain and Nivola himself, who played the deliciously slimy D.A. this past season in “American Hustle.”

Not at the screening, but look for hilarious cameos in “Doll & Em” from Susan Sarandon, John Cusack and Andy Garcia.

PS Emily told me the third and final season of “The Newsroom” begins in a few days. And no, she has not seen a script, and has no idea what this season’s story will be.
