Who would you be if you could choose your looks, identity, body type, gender and even your historical era? Prepare for questions like these and more in the offbeat and provocative film “Molotov Alva and His Search for the Creator: A Second Life Odyssey” (7 p.m., Cinemax).

Reported to be the first film ever created in the virtual reality of the “Second Life” community, “Molotov” is the story of filmmaker Douglas Gayeton, who abandons his real life, or, as he calls it, his “carbon life,” to live exclusively in his Second Life as his avatar, or alter ego, Molotov Alva.

Unlike many in the computer-animated Second Life world, he chooses a body type that resembles his own human form. He immediately creates a fancy beach house for himself filled with the latest gadgets and appliances. But this sudden cyber abundance makes him wonder: I don’t need to eat, so why do I need a brand-name range and an expensive kitchen? What good is a stylish bedroom for a character who doesn’t need sleep?

Freed of the necessities of everyday living, Alva discovers that Second Life can be both a liberation and a burden. His “who-am-I?” and “who created-this-world?” curiosity leads him on a pilgrimage with another offbeat Second Life seeker as well as into the “arms” of a woman who may turn out to be the greatest relationship of his life.

We’re often reminded that people can lose themselves in online realms like Second Life. “Molotov Alva” shows us that they can find themselves, as well. Or at least try.

¢ The last two seasons of “The Office” (8 p.m., NBC) have ended with strong, memorable episodes, both involving key moments in Jim and Pam’s unfolding romance. Now that they are a relatively happy couple, what can “The Office” writers come up with to keep us thinking about all summer?
