At a loss for what to watch this week? From new DVDs and Blu-rays, to what's streaming on Netflix, we've got you covered.

New Video on Demand, Rental Streaming, and Digital Only

"Insurgent"
Shailene Woodley, Theo James and Kate Winslet return as Tris, Four and The Wicked Witch of Erudite in this sequel to "Divergent," which has its Digital HD premiere on July 21, ahead of the DVD/Blu-ray/On Demand release on August 4. The Digital HD/3-D Blu-ray Combo Pack/Blu-ray include more than four hours of bonus material, including audio commentary with producers Doug Wick and Lucy Fisher; "Insurgent Unlocked: The Ultimate Behind-the-Scenes Access" feature-Length documentary; and five featurettes: "Diverging: Adapting Insurgent to the Screen," "From Divergent to Insurgent," "The Others: Cast and Characters," "The Train Fight Unlocked," and "The Peter Hayes Story."

"Before We Go"
Chris Evans -- aka Captain America -- makes his directorial debut and also co-stars in this romance with Alice Eve. She plays a woman who races to catch a train from NYC to Boston and, on the way, she's robbed and left alone and lost in the city. If only there were a hot guy around to help her! This movie is scheduled for a limited release in theaters on September 4, but iTunes has it well in advance on July 21. So that's pretty cool.

"Veep"
Find out why Julia Louis-Dreyfus was just nominated for still another Emmy (she's been nominated 20 times and won 5!) when Season 4 of this HBO gem makes its Digital HD debut on July 20. Julia plays former Veep/now acting POTUS Selina Meyer, but will voters chose to elect her president or will she have to pass the baton to one of her rivals? (One of those rivals includes a key ally, Season 4 newbie -- and total scene-stealer -- Hugh Laurie.)

New on DVD and Blu-ray

"What We Do in the Shadows"
Do yourself a favor and check out this hilarious mockumentary about the lives of three vampires from Jermaine Clement ("Flight of the Conchords") and Taika Waititi ("Eagle vs. Shark"). The Blu-ray has more than two hours of extras, including behind-the-scenes footage, commentary from writers/directors Clement and Waititi, and deleted scenes. In case you need convincing, here's the trailer:

"Kung Fu Killer"
Teddy Chen directs this action movie which has a great title and a pretty badass premise: A vicious serial killer is targeting top martial arts masters -- which sounds like a death wish in the making -- and convicted criminal and kung-fu master Hahou (Donnie Yen) is the only one with the skills to stop him. But can Hahou be trusted? Blu-ray bonus features include a behind-the-scenes featurette exploring how they made some of the key sequences.

New on Netflix

"Teacher of the Year"
There's not a whole lot out on Netflix this week, to be honest, but this 2014 comedy will be available July 23. Matt Letscher stars as Mitch, who wins the California Teacher of the Year award and gets a tempting offer that might prompt him to leave his job. Keegan-Michael Key and Sunny Mabrey co-star.

"The Guest"
Dan Stevens leaves Matthew Crawley waaaayyyy behind in this dark thriller, which is available July 25. Dan plays David, a young soldier who arrives on the doorstep of the Peterson family, claiming to be a good friend of their son, who died in action. But all may not be as it seems, and when people in town start dying, it's time to start questioning "the guest."

TV Worth Watching

"Zoo" (Tuesday on CBS at 9 p.m.)
We're up to Episode 4 of the James Patterson adaptation and things are getting wild. Get it -- wild? Here all week! In "Pack Mentality," CBS notes, "Jackson (James Wolk), Abraham (Nonso Anozie), Mitch (Billy Burke), Jamie (Kristen Connolly) and Chloe (Nora Arnezeder) are tasked by a top intelligence agent to find the cause of the strange animal behavior around the world. When the team travels to Mississippi to investigate the wolf attack on the prison, Mitch and Abraham break off to catch one of the wolves, and Chloe, Jackson and Jamie discover that death row inmate escapee Evan Lee Hartley (Marcus Hester) might somehow be involved in the attack."

"Sharknado 3: Oh Hell No!" (Wednesday on Syfy at 9 p.m.)
Is this really "TV worth watching?" No. Oh hell no, even. But it's summer. And it's worth following just for the absurdity of it all -- and to check Twitter to see what inspired tweets may emerge from your fellow guilty pleasure lovers. In this round, Ian Ziering, Tara Reid and Cassie Scerbo return, with David Hasselhoff, Bo Derek, Ryan Newman, and Jack Griffo joining the fun.

"I Am Cait" (Sunday on E! at 8 p.m.)
Caitlyn Jenner's eight-part docuseries begins July 26. Follow Cait's search for her "new normal" and see how her transition impacts those closest to her.
