Rat Pack

The talk of the town, and the toast of Hollywood. In the '60s, the Rat Pack—consisting of Frank Sinatra, Dean Martin, Sammy Davis Jr., Peter Lawford, and Joey Bishop—were among the most glamorous of Hollywood's A-list. They often came together at Humphrey Bogart's Holmby Hills home, where other stars such as Elizabeth Taylor and Judy Garland also spent time. 

Though they themselves never referred to their group as the Rat Pack, the name was adopted by the media, allegedly after Lauren Bacall (Bogart's wife) described them as "a goddamn rat pack". The group's popularity had soared during their heyday, so much so that they starred together in the movie Ocean's 11, which had a 2001 remake and multiple franchises. 

 

Brat Pack

New York Magazine first coined the term "Brat Pack" in 1985. The group consisted of actors who often worked together in iconic '80s films. These included Molly Ringwald, Anthony Michael Hall, Rob Lowe, Emilio Estevez, Demi Moore, Judd Nelson, Andrew McCarthy, and Ally Sheedy. Though each actor and actress has gone on to create a variety of films through multiple genres, those who remember them in the '80s will likely love them for their slew of coming-of-age films that are still entertaining to this day.

Team Apatow

In 1999, Seth Rogen and Jason Segel worked together on the short-lived sitcom Freaks and Geeks, produced by Judd Apatow. This would be the birth of Team Apatow, a group consisting of Apatow himself, Seth Rogen, Jason Segel, Jay Baruchel, Paul Rudd, and Jonah Hill. Many fans delighted in the movies of these six funnymen, laughing at films such as Knocked Up and Superbad, where Hill played a fictionalised version of Rogen. 

SNL Ladies

Saturday Night Live may not be everyone's cup of tea in terms of humour, but you have to admit: they birthed many great stars. Perhaps the most iconic group of friends to have been formed throughout the show is the one that included Tina Fey, Amy Poehler, Rachel Dratch, Kirsten Wiig, and Maya Rudolph. The group have been in multiple projects together, though never have all of them appeared on-screen simultaneously. Most fans notice that they often work in pairs during projects, such as Fey and Poehler's work together in Mean Girls, Wiig and Rudolph's on-screen friendship in Bridesmaids, and Dratch and Poehler's roles in Parks and Recreation

Taylor Swift's Squad

Who can forget Taylor Swift's #Squad in the mid-2010s? All high-profile women, Taylor Swift's girl squad included the likes of Selena Gomez, Cara Delevingne, Martha Hunt, Karlie Kloss, Gigi Hadid, Lily Aldridge and Lena Denham. Sadly enough, Swift has received incredible backlash for her group of friends; she even commented on the sexist undertones of it all saying, "I thought it was going to be we can still stick together, just like men are allowed to do.

The patriarchy allows men to have bro packs. [For women, however], it’s assumed that we hate each other." Fortunately, Swift seems to still remain friends with the ladies, though prefers to keep a lower profile these days; they all starred in her music video, Bad Blood, together.
