2. New Zealand nursing home residents do move-for-move remake of music video for Pharrell's "Happy"

These nursing home residents show off their moves in this viral video making the rounds this week.

Some 60 residents and staff members from the Diana Isaac Retirement Village in Christchurch, New Zealand, take on Pharrell Williams' hit. And they did it move-for-move just as Pharrell does it in his music video.

It's bound to make you smile -- and sorta makes us want to move to Christchurch when it comes time to retire. These guys are having too much fun.

3. First trailer for "The Hobbit: The Battle of the Five Armies" released

"Will you follow me, one last time?"

That's the question Thorin Oakenshield asks in the new trailer for "The Hobbit: The Battle of the Five Armies," which was first unveiled at Comic-Con and arrived online Monday.

The final film in Peter Jackson's "The Hobbit" trilogy concludes the adventures of Bilbo Baggins (Martin Freeman), Thorin Oakenshield and the Company of Dwarves. The heroes of Middle Earth must now contend with the ferocious dragon Smaug (Benedict Cumberbatch) and the fast-mobilizing forces of Sauron.

4. A capella group Home Free's music video of Johnny Cash's "Ring of Fire" is a viral hit

"Ring of Fire" goes a capella with this version of the Johnny Cash classic performed by Home Free. The five-member group features Pentatonix's Avi Kaplan. It's way different from the Cash version we all know and love -- and worth a listen:

5. Teaser trailer released for "The Hunger Games: Mockingjay - Part 1"

The first official teaser trailer for "The Hunger Games: Mockingjay - Part 1" arrived online, and it shows Katniss Everdeen (Jennifer Lawrence) ready to join the rebellion against the Capitol.

6. Orlando Bloom and Justin Bieber get into altercation

Orlando Bloom and Justin Bieber reportedly got into a bit of scuffle in Ibiza, Spain, on Wednesday, according to multiple reports.

TMZ has footage of the alleged altercation, which supposedly took place at Cipriani restaurant where both stars had been dining -- separately. An eyewitness told the site that after the two exchanged words, Bloom, 37, attempted to punch the 20-year-old Canadian pop star.

There were also reports that words were exchanged over Bloom's ex, model Miranda Kerr. Either way, the altercation set off a flurry of talk and even a few jokes:

8. Nude Charlie Hunnam appears in video with "Sons of Anarchy" castmembers to explain absence from 2014 Comic-Con

Actor Charlie Hunnam didn't make it to Sunday's "Sons of Anarchy" panel at Comic-Con in person -- but he sure made up for his absence. Instead, he appeared virtually in a video alongside castmates Tommy Flanagan, Mark Boone Junior and Kim Coates. And it was pretty hot. Oh those arms!

Way to drum up buzz for the upcoming season:

9. Syfy's "Sharknado 2: The Second One" Brings More Sharks, More Gore, More Stars

"Sharkando 2: The Second One" stormed on to Syfy Wednesday night -- and quickly became a trending topic in Twitter and turned into a big ratings hit for the network.

The sequel, which comes on the heels of last summer's original TV movie, found Tara Reid and Ian Ziering reprising their roles alongside plenty of guest stars, including Matt Lauer, Mark McGrath, Kelly Osbourne and more.

"We shot this movie in 18 days, but the story has expanded. Once [production company] The Asylum realized what they can do with a few more dollars in the budget the script reads like a $100 million blockbuster," Ziering told CBS News. "From halfway through the first page, it starts. And it doesn't let up ever."

Relive the ridiculousness all over again:

10. Kim Kardashian new mobile game lets you be a star, too

She already has a reality show empire, but now Kim Kardashian is taking over the mobile game world, too. "Kim Kardashian: Hollywood" from Glu Mobile, which launched earlier this summer, is picking up steam fast. The game lets users create an avatar that can work to gain virtual A-list status. Basically, your avatar mingles with celebrities, goes on photo shoots and dons trendy clothing.

Sounds kinda silly, right? But this game is raking in major bucks. According to the New York Times, it earned $1.6 million in revenue during its first five days.
