Most actors find it hard to make the transition from TV to the silver screen but Cobie Smulders makes it look easy.
The Canadian actress landed her first major movie role in the Marvel action film The Avengers playing S.H.I.E.L.D. agent Maria Hill.
Smulders admits she couldn't believe her luck when she was offered the role starring alongside Hollywood heavyweights such as Robert Downey Jr, Chris Hemsworth, Mark Ruffalo and Samuel L. Jackson.
In fact, the 30-year-old was so eager to be a part of the popular franchise she signed on without seeing a script or knowing who she was playing.
Her character works alongside Nick Fury (Jackson), the head of peacekeeping organisation S.H.I.E.L.D. who enlists the help of Iron Man, the Hulk, Thor and Captain America to save the world from annihilation.
Smulders says preparing for a blockbuster film pushed her out of her comfort zone.
"It's hard to relate them to each other because I have been doing How I Met Your Mother for so long that the character I play, Robin, I can click in and out of it very quickly," she says over the phone from Los Angeles.
"The cool thing about Avengers for me was I really had to force myself to get into the physicality of this person. She is an officer, she's in shape so I was boxing three times a week.
"She holds herself in a certain way and she means business so I had to always be aware of that when shooting Avengers. It was cool to take on a character that was that physically different."
Born in Vancouver, Smulders started off as a model before landing bit parts on TV. Her big break came in 2005 when she bagged the role of news anchor Robin Scherbatsky in How I Met Your Mother.
Set in New York, the comedy centres around hopeless romantic Ted (played by Josh Radnor), the story of how he met the mother of his children and the exploits of his friends Marshall (Jason Segel), Barney (Neil Patrick Harris), Lily (Alyson Hannigan) and Robin.
Having been in relationships with both Barney and Ted during the course of the show, Robin is currently single and throwing herself into her career. She discovered she was unable to have children midway through the seventh season and, despite not wanting to get married and have kids, the news hit Robin hard.
After more than 150 episodes, Smulders still enjoys playing the independent Robin and was keen to tackle important issues, like the infertility storyline, on the show.
Smulders, who has a three-year-old daughter with Saturday Night Live comedian Taran Killam, says the issue was one she could relate to.
"I have countless friends and family members who are going through similar issues where they can't get pregnant or they have lost a child," she says. "It's very nice to have that for people to watch, relate to and hopefully talk about so they don't feel alone."
With only one more season to go before the TV show wraps, fans are keen to know not only who the infamous mother is, but if Barney and Robin get back together. The coupling proved popular with viewers but the writers have kept her in the dark
"The fans love Robin and Barney together but I don't know. I can't quite say because they don't tell us much," she says.
"But I can say it is a definite possibility. It'll be very hard (when the show finishes) but I know that the writers will end it in a way that is beautiful and that the fans will really love. <div class="endnote">
