2000–2004: Breakthrough with Wolverine and the X-Men
Jackman had his breakthrough role playing Wolverine in Bryan Singer's X-Men (2000)—a superhero film based on the Marvel Comics team of the same name. Co-starring Patrick Stewart, James Marsden, Famke Janssen and Ian McKellen, the film tells the story of a group of mutants, whose superhuman powers make them distrusted by normal humans, but who fight to protect humans from villains. The role was originally written for Russell Crowe who instead suggested Jackman for the part. Jackman says that his wife advised him against taking on the role, as she found it "ridiculous". He initially studied wolves to develop his character, as he thought that Wolverine alluded to wolves. X-Men was successful at the box-office, earning US$296 million. The role earned him a Saturn Award for Best Actor.
Wolverine was tough for Jackman to portray because he had few lines, but much emotion to convey in them. To prepare, he watched Clint Eastwood in the Dirty Harry movies and Mel Gibson in Mad Max 2. "There were guys who had relatively little dialogue, like Wolverine had, but you knew and felt everything. I'm not normally one to copy, but I wanted to see how these guys achieved it." Jackman was adamant about doing his own stunts for the movie. "We worked a lot on the movement style of Wolverine, and I studied some martial arts. I watched a lot of Mike Tyson fights, especially his early fights. There's something about his style, the animal rage, that seemed right for Wolverine. I kept saying to the writers, 'Don't give me long, choreographed fights for the sake of it. Don't make the fights pretty." Jackman also had to get used to wearing Wolverine's claws. He said, "Every day in my living room, I'd just walk around with those claws, to get used to them. I've got scars on one leg, punctures straight through the cheek, on my forehead. I'm a bit clumsy. I'm lucky I didn't tell them that when I auditioned."
At 6 ft 2 in (1.88 m), Jackman stands 11 in (28 cm) taller than Wolverine, who is said in the original comic book to be 5 ft 3 in (1.60 m). Hence, the filmmakers were frequently forced to shoot Jackman at unusual angles or only from the waist up to make him appear shorter than he actually is, and his co-stars wore platform soles. Jackman was also required to add a great deal of muscle for the role, and in preparing for the fourth film in the series, he bench-pressed over 136 kg (300 lb).
Jackman reprised his role in 2003's X2, 2006's X-Men: The Last Stand, and the 2009 prequel X-Men Origins: Wolverine, where Troye Sivan played the younger version of James Howlett. He also cameoed as Wolverine in 2011's X-Men: First Class. He returned for the role of Wolverine again in 2013's The Wolverine, a stand-alone sequel taking place after the events of X-Men: The Last Stand, and reprised the character in the 2014 sequel X-Men: Days of Future Past and briefly in the 2016 follow-up X-Men: Apocalypse. In 2015, Jackman announced that the 2017 sequel to The Wolverine, Logan, was the final time that he would play the role. It earned him the Guinness World Record of "longest career as a live-action Marvel superhero", although this record has since been surpassed.
Jackman starred as Leopold in the 2001 romantic comedy film Kate & Leopold, a role for which he received a Best Actor Golden Globe nomination. Jackman plays a Victorian English duke who accidentally time-travels to 21st-century Manhattan, where he meets Kate (Meg Ryan), a cynical advertising executive. In 2001, Jackman starred in the action thriller Swordfish alongside John Travolta and Halle Berry, marking his second collaboration with Berry following X-Men (2000) and preceding three further appearances together in the X-Men film series. He also hosted an episode of Saturday Night Live in 2001.
In 2002, Jackman sang the role of Billy Bigelow in the musical Carousel in a special concert performance at Carnegie Hall with the Orchestra of St. Luke's. In 2004, Jackman won the Tony Award and the Drama Desk Award for Outstanding Actor in a Musical for his 2003–2004 Broadway portrayal of Australian songwriter and performer Peter Allen in the hit musical The Boy from Oz, which he also performed in Australia in 2006. In addition, Jackman hosted the Tony Awards in 2003, 2004, and 2005, garnering positive reviews. His hosting of the 2004 Tony Awards earned him an Emmy Award for Outstanding Individual Performer in a Variety, Musical or Comedy program.
After 2003's X2, Jackman played the title role of monster killer Gabriel Van Helsing in the 2004 film Van Helsing. Jackman and the film were noted in Bruce A. McClelland's book Slayers and Their Vampires: A Cultural History of Killing the Dead.
