Yes, "Austin Powers: International Man of Mystery" is the first movie in the Austin Powers franchise. Released in 1997, it introduces the character of Austin Powers, a British spy who is frozen in the 1960s and thawed out in the 1990s to battle his nemesis, Dr. Evil. The film parodies spy films, particularly the James Bond series, and became a cult classic, leading to two sequels: "Austin Powers: The Spy Who Shagged Me" (1999) and "Austin Powers in Goldmember" (2002).

In "Austin Powers: International Man of Mystery," Mike Myers plays three characters: Austin Powers, a groovy British spy; Dr. Evil, his arch-nemesis; and Fat Bastard, a large, Scottish henchman. His performances as these distinct characters contribute significantly to the film's comedic style and appeal, showcasing Myers' versatility as a comedic actor. The film, released in 1997, is a parody of the spy genre and has become a cult classic.

As of October 2023, there has been no official announcement regarding "Austin Powers 4." Mike Myers, the creator and star of the franchise, has expressed interest in returning to the role, but no concrete plans have been confirmed. In interviews, he has mentioned that he would be open to revisiting the character if the right idea comes along. Fans continue to hope for a sequel, but for now, the future of "Austin Powers 4" remains uncertain.

As of my last update in October 2023, "Austin Powers: International Man of Mystery" is available for streaming on platforms like HBO Max and Amazon Prime Video. However, streaming availability can change, so it's a good idea to check the specific service in your region or use a streaming aggregator to confirm its current status.
