How I Met Your Mother star Josh Radnor has taken his talents to the big screen, by writing, directing AND starring in this new comedy-drama, alongside Elizabeth Olsen. 

Zac Efron is also part of the cast, although we tried really hard, and couldn't actually spot him in the trailer. Weird.

Ted Josh stars as 35 year old Jesse, who returns to college to visit his former teacher, only to find himself falling for a 19-year-old student, played by Elizabeth. 

And while a mahoosive age difference may not be a big deal for the likes of Harry Styles and Peter Andre, the lovestruck pair struggle to come to terms with their attraction.

From watching the trailer, we have deduced the following three things:

1. The soundtrack sounds BOOM TING.

2. We fancy Josh Radnor.

3. Elizabeth Olsen is giving Emma Stone a run for her money in the 'Actress the Sugarscape team would most like to be' stakes.

Watch and see for yourselves here!
