The summer movie blockbuster season officially opens as Peter Parker and the gang whip back into action with the third and highly anticipated chapter in the Spider-Man franchise. PEOPLE takes a look at all the action, plus other events to watch for in the coming week:

TUESDAY, MAY 1: You may remember her 2004 single “8th World Wonder,” and now you’re probably wondering just what happened to Kimberley Locke. Well, she’s back, and the American Idol season 2 finalist (she earned third place) has a full album of new material – Based on a True Story. Led by the powerful and soulful first single “Change,” Locke is already gunning for chart success. Even better, the follow-up to her 2004 debut disc One Love finds the singer turning inward, reflecting on her relationships and co-writing at least eight of the album’s tracks. Plus, she’s keeping busy with other projects, including an upcoming stint on VH1’s Celebrity Fit Club.

He’s been Stanley Kowalski, the Godfather and Superman’s dad, but the real Marlon Brando can be a confounding puzzle. Now Turner Classic Movies attempts to unravel the mystery behind the man with a documentary, brando.”, featuring interviews with celebrity pals and costars like Edward Norton, Al Pacino and John Travolta. Plus, more good news for Brando fans: The documentary spans two successive nights (TCM, 8 p.m. ET) and it incorporates never before seen footage of the star, clips of his iconic roles and even interviews with his family.

THURSDAY, MAY 3: Could this be the end of Dr. Addison Montgomery? Or is it a new beginning? After weeks of tip offs that Seattle’s best neonatal surgeon – played by actress Kate Walsh – will be heading for greener pastures, Grey’s Anatomy (ABC, 9 p.m. ET) reveals an alternative future for the redheaded spitfire by rolling out a two-hour episode that will also serve as a pilot of the proposed spinoff co-staring Taye Diggs. So, can we already dub him McTasty?

FRIDAY, MAY 4: Cool off in the movie theaters as the summer blockbuster season officially arrives courtesy of Spider-Man 3, the hotly anticipated action flick starring Tobey Maguire and Kirsten Dunst. Before the film even opens, though, a massive media blitz begins with talk show appearances and promo galore. Check out Dunst on Live with Regis and Kelly on May 2. On screen, Spidey battles a fleet of villains – this time including the Sandman (Thomas Haden Church) and Venom (Topher Grace) – all while balancing his own relationship with girlfriend Mary Jane in the process. But, of course, that’s what makes him a superhero.
