The "Terminator" star's next film, "Expendables 2" will arrive in theaters August 17 and in October he will begin production on "Breacher" in Atlanta and will release and promote a memoir at the same time.

Schwarzenegger recently attended his first Comic-Con to promote "Expendables 2" with director/co-star Sylvester Stallone, Terry Crews and Dolph Lundgren.

On the panel, he was asked about a possible sequel to his film "Twins" tentatively titled "Triplets":

"I think that we've moved it along," he replied according to The Hollywood Reporter. "Ivan Reitman has shown interest again, and Universal loves the idea. We are now looking for a great writer to write the sequel. I think it would be hilarious."

"Breacher" is an action thriller film that will be directed by David Ayer ("Training Day") and co-stars Sam Worthington ("Avatar") Terrence Howard ("Iron Man" and "Red Tails") and Dawn Olivieri ("Vampire Diaries", "House of Lies"). The script will be written by Skip Woods who wrote "Swordfish."

The story line involves 10 DEA agents who steal goods during an enforcement operation and eventually get killed one by one.

Schwarzenegger is working also on a memoir tentatively titled "Total Recall."  The book's publisher is Simon & Schuster and will arrive in stores in October 2012, according to The New York Times.

As an immigrant from Austria, he used his bodybuilding to gain fame in the United States. He landed roles in several blockbuster movies, married Maria Shriver who is a Kennedy and became governor of California. There is no confirmation if the book will detail his alleged infidelities including fathering a child with his former maid.

As for his romantic life, the 65-year-old was spotted recently hanging out with a 25-year-old woman, according toTMZ.
