Cobie Smulders is winding down her run on How I Met Your Mother. Her character, Robin Sherbatsky (fka Canadian teen-pop sensation Robin Sparkles), will likely wed Neil Patrick Harris' Barney Stinson and then move aside for Josh Radnor's Ted Mosby to finally meet his freaking wife-to-be after 8 seasons of his meandering stories. She's already got one foot in the door when it comes to a possible transition to the big screen: She played Agent Maria Hill in 2012's summer blockbuster The Avengers and she's appearing in the upcoming Delivery Man with Vince Vaughn.
Smulders has a pretty good repertoire. She can do comedy (obviously) and she also showed that she can do action - the opening scene in The Avengers showed that. It'll be interesting to see how it all turns out in Delivery Man and what direction she decides to go. Smulders does have an avenue to pursue if Delivery Man does badly and she realizes that there is the possibility that she would be paid better and recognized more on the smaller screen: Agents of S.H.I.E.L.D. She appeared in the pilot and I'm sure they would bring her back if her shooting schedule allowed. After all, the whims of audiences can be very hard to predict; one actress can have a long and successful movie career while another can only do a few movie projects, if anything, and then go back to television, if the opportunity presents itself. There's always commercials, too.
The window for opportunity in Hollywood can be really, really small - sometimes it feels like a doggie door, and it can slam shut very quickly, because there are so many hungry actors and actressess (both literally and figuratively) out there that will grab any opportunity. She may be a known face now, but she also has to see that the public memory can be very fleeting. She's got to know that she's swimming with a lot of sharks and the comprtition is fierce.
Let's just hope Smulders can do a show years from now called How I Made A Lot Of Money In Hollywood. There could be eight seasons of her telling her stories about that and she would be a lot more fun to listen to than Mosby.
