Action film is a film genre where one or more heroes is thrust into a series of challenges that require physical feats, extended fights and frenetic chases. They tend to feature a resourceful character struggling against incredible odds, which may involve life-threatening situations, an evil villain, and/or being pursued, with victory achieved at the end after difficult physical efforts and violence. Story and character development are generally secondary to explosions, fist fights, gunplay and car chases.

While action films have traditionally been a reliable source of revenue for movie studios, relatively few action films garner critical praise, mainly because of their two-dimensional heroes or villains. Nevertheless, Hollywood has been making more action films than ever, in part because advancements in CGI have made it cheaper and easier to create action sequences and other visual effects that required professional stunt crews and dangerous staging in the past. However, audience reactions to action films containing significant amounts of CGI have been mixed, and films where computer animation is not believable are often met with criticism.

Nathaniel Joseph "Nature" Ruess (February 26, 1982) is an American indie/indie pop singer-songwriter from Arizona. Ruess was the singer of The Format and currently lead vocalist of the band Fun.

Nate was born February 26, 1982 in Iowa City, Iowa. He was the youngest of two children, his sister Libbie being one year older.

In 1986, his family moved to a farm in Glendale, Arizona, where he remained throughout his childhood. He attended Deer Valley High School and graduated in 2000. Having an uncle, John Ruess, who performed on Broadway, Ruess was always somewhat interested in music and performing. He joined punk bands in high school and, upon graduation, chose to pursue music instead of attending college. He never took formal singing lessons or learned to play an instrument and was often told by peers that he lacked the talent to make it professionally. He took a job in a law firm as a way to support himself while he pursued his musical ambitions.

In 2001, at the age of 19, he launched the band The Format with his longtime best friend, Sam Means. This was his first musical endeavor to garner widespread attention.

Raised in Honolulu, Hawaii by a family of musicians, Mars began making music at a young age. He performed in various musical venues in his hometown throughout his childhood. He graduated from high school and then moved to Los Angeles, California to pursue a musical career. Mars produced songs for other artists, joining production team The Smeezingtons.

Mars had an unsuccessful stint with Motown Records, but then signed with Atlantic Records in 2009. He became recognized as a solo artist after lending his vocals and co-writing the hooks for the songs "Nothin' on You" by B.o.B, and "Billionaire" by Travie McCoy. He also co-wrote the hits "Right Round" by Flo Rida featuring Ke$ha, and "Wavin' Flag" by K'naan. In October 2010, he released his debut album, Doo-Wops & Hooligans. Anchored by the worldwide number-one singles "Just the Way You Are" and "Grenade", the album peaked at number three on the Billboard 200. Mars was nominated for seven Grammys at the 53rd Grammy Awards, winning Best Male Pop Vocal Performance for "Just the Way You Are".
