Brandon Routh

 ( Male Actors From Iowa ) 

Routh, then 24, had previously auditioned for director McG and was spotted by Singer after he viewed Routh's videotaped audition. Singer, who has since stated that Routh was the embodiment of "our collective memory of Superman," was impressed by Routh's resemblance to the comic book icon and found the actor's humble Midwestern roots perfect for the role, as well as his "combination of vulnerability and confidence", which Singer said reminded him of Christopher Reeve. Singer decided to cast Routh after the two met on August 13, 2004, but did not tell Routh until two months later, when Routh's casting was announced in October 2004, making him an "instant celebrity".

Before filming began, Routh bulked up for the role, gaining 22 pounds to reach a high of 218 pounds. Filming for Superman Returns began in Sydney in February 2005. The film was released in the U.S. on June 28, 2006, and earned decent reviews from most critics, but was a box office disappointment, grossing only $200 million in the US compared to its estimated budget of $270 million. Routh was signed on to appear in two potential sequels, but due to mediocre box office results those never materialised.

Reviews of Routh's performance were generally positive, with Newsweek noting he "effortlessly lays claim to the iconic role." On the other hand, film critic Roger Ebert felt that "Routh lacks charisma as Superman, and I suppose as Clark Kent, he isn't supposed to have any."

At the 2006 Spike TV Awards, Routh won the award of "Best Superhero" as Superman in Superman Returns, beating out among others, Hugh Jackman as Wolverine.

In August 2008, Warner Bros. officially announced they intended to reboot the Superman franchise. Routh was still set to reprise the role, according to DC Comics president Paul Levitz. In 2009, however, Routh's contract to play Superman in another film expired, but he said at the time that he would like to return if given the chance. However, British actor Henry Cavill was cast to play Superman in the reboot of the series, Man of Steel.

Routh appeared in the independent romantic drama Fling (formerly titled Lie to Me) (2008), co-starring his wife Courtney Ford, and the ensemble film Life is Hot in Cracktown (2009).

Routh was signed to star in The Informers (2009), an Ensemble cast film based on Bret Easton Ellis' The Informers, with Kim Basinger, Amber Heard, and Billy Bob Thornton, but his scenes ended up scrapped with the decision to excise the "vampire" subplot from the film entirely.

At Comic Con 2008, it was revealed Routh was to have a cameo in the Kevin Smith comedy Zack and Miri Make a Porno – he instead appeared as a minor character, Bobby Long – and would serve as a judge on Platinum Studios 2008 Comic Book Challenge. In addition, he has a cameo where he plays himself in the Bollywood film Kambakkht Ishq (2009).

Routh played Todd Ingram in the action comedy Scott Pilgrim vs. the World (2010) which was directed by Edgar Wright, based on the Scott Pilgrim series by Canadian artist Bryan Lee O'Malley.

In 2014, Routh once again played a superhero for DC Comics as Ray Palmer / The Atom on The CW's Arrow. He was a recurring character throughout season three.

In January 2015, Arrow co-creator and executive producer Greg Berlanti stated that they were in the midst of "very early" preliminary talks for an additional spin-off series centred on Ray Palmer/The Atom.

In the superhero series Legends of Tomorrow (2016–2022), Routh co-starred as The Atom, along with Arthur Darvill, Wentworth Miller, Victor Garber, and Caity Lotz.

Routh reprised his roles as both Ray Palmer / The Atom and as Clark Kent / Superman in the 2019–2020 Arrowverse crossover "Crisis on Infinite Earths", affected by events adapted from the Kingdom Come storyline. The suit he wore as Superman was based on the one worn by the storyline's version of the character. The following month, it was announced that Routh would depart Legends of Tomorrow as a series regular during the fifth season. His final episode as a series regular was "Romeo v. Juliet: Dawn of Justness".

Following this, Routh made three returns to the franchise. First, he returned to Legends for its 100th episode, and to The Flash for the first part of its season eight-opening event "Armageddon". He would then return in the season's eighteenth episode, "The Man in the Yellow Tie".
