The new Marvel comics superheroes flick, “The Avengers: Age of Ultron,” has come to The Harbor Theatre this week. Fans of these characters — Iron Man, Black Widow, the hunky duo of Thor and the Incredible Hulk, Hawkeye, Captain America, Quicksilver, Klaw, War Machine, The Falcon and, new Avenger, as of this film, Scarlet Witch — will no doubt be swept away by this intense, high action film.

But then, the lives of superheroes have never been dull — from what I've heard, anyway.

At the outset I must admit this film is not a genre that calls to me. So, bear with me as I explain the plot.

In this Avengers installment, Tony Stark, a.k.a. Iron Man (Robert Downey Jr.) takes his experiments with artificial intelligence (AI) to new heights. The superheroes bring a 'scepter' (which apparently is the 'mind' stone of the six infinity stones inside) back to Stark's laboratory from an assignment in Germany.

Stark finds it too tempting to leave alone. Aided by his computer Jarvis, he intends to create a robot, Ultron (James Spader), out of Stark's uniformly unique armor, possessing artificial intelligence to be part of his vision of a global peacekeeping mission.

“I see a suit of armor around the world ... the world needs Ultron,” Stark says. “It's peace in our time.”

His experiments hit a screeching halt when it comes to the integration part of the experiment. Jarvis tells Stark to get ready for a party he's hosting at Stark Towers and that he, Jarvis, will continue trying to figure out they have missed. And then everything starts to get AI strange.

Ultron, in just his AI 'form' (consciousness) begins talking to a surprised Jarvis, then reading what's in Jarvis' 'mind' and reciting Stark-speak. Jarvis keeps saying he will call Stark in. Finally Ultron says aloud that the peacekeeping mission in our time is too much.

Ultron is in distress. (Oh boy, here we go — it's “Hal” all over again.)

However, Ultron's not in so much distress that he cannot manage to take over Jarvis — how's that for integration?

Ultron is a hostile, aggressive version of Jarvis. Already he doesn't sound like a team player.

He creates his own mechanical form from items handy in Stark's laboratory and then introduces himself to Stark, his fellow Avengers, and the other guests at the party in a most impolite manner by crashing it — literally.

Ultron tells the Avengers they are not worthy to be superheroes because they are killers.

Ultron further informs them that he will be taking them down — all of them. They all must be destroyed because they are the reason peace doesn't exist ... the Avengers and humankind in general.

“You want to save humanity, but how can you if you don't allow them to evolve?” Ultron asks and then leaves.

The Avengers discover he has read all of Stark's files and has escaped through the Internet. (Oh great — I'm not sure I like the idea of thinking about AI out there in cyberspace.)

Ultron winds up in Germany where the Avengers picked up the scepter. In a church there he has a nice little chat with Pietro/Quicksilver (Aaron Taylor-Johnson) and Wanda Maximoff/Scarlet Witch (Elizabeth Olsen), twins used in a German scientist's experiments in war time (which sounds horrifyingly familiar) and the result is that they both have extraordinary powers. She is capable of telekinesis, weaving a spell and protective, deadly energy she can produce at will; he is quick — quicker than the speed of light, he's quicksilver.

Ultron tells them how useful they will be: “Pietro, you will herd the Avengers, and Wanda will destroy them from the inside.”

Ultron later pays a visit to a genetic research facility in South Korea, seeking to use the “regeneration cradle” on himself.

Just as action films have the climatic car chase scene, sci-fi has its own version: the big combat scene. At one point the superheroes are all grouped together fighting Ultron's army as the cameras move at 180 degree angle, the music cues up — the ultimate good versus evil, we shall overcome moment. Not to mention the larger than life fight scene between Iron Man and an out of control Hulk.

This movie is filled with fast action moments — don't blink.

The film has both budding romance, Black Widow and Hulk; mature love with Hawkeye, his until-this-film unknown wife and mother of his two children, oh, make that three (one's on the way); and the familial love shared by the twins.

The special and visual effects are appropriately out-of-this-world, cinematographer Ben Davis' skill adds to the depth of both the effects and story itself.

And, I can't talk about visuals and leave out the cast! Downey is always delightful on a big screen. He is joined by Chris Hemsworth as Thor (gotta dig that hair), Scarlett Johanson as Natasha Romanoff/Black Widow, Mark Ruffalo as Bruce Banner/Hulk, Chris Evans as Steve Rogers/Captain America and Jeremy Renner as Clint Barton/Hawkeye.

Oh, and, you might want to sit through the credits — there's a teaser preview of what's to come in the next installment. Well, you know there has to be; there's still four infinity stones out there and that means four more MARVELous adventures have yet to be had. Hey, does that last line qualify as a spoiler?

“The Avengers: Age of Ultron” opens Thursday, April 30 at 7 p.m. at The Harbor Theatre, 185 Townsend Avenue in Boothbay Harbor. It screens at 7 p.m. on May 1, 2, 6 and 7 with a 2 p.m. matinee on May 3.
