Jason Segel and Emily Blunt play lovebirds who delay their marriage big time in the new film, The Five-Year Engagement.

The romantic comedy, out in April, released its first trailer on Wednesday.

Segel and Blunt play Tom and Victoria, a newly-engaged couple that gets interrupted over and over again by a new job, new location and family drama.

Blunt, 28, keeps her English accent in the film, which also stars Alison Brie (Mad Men), Rhys Ifans, Chris Pratt, Mindy Kaling and Chris Parnell.

The Five-Year Engagement is written by Segel and Nicholas Stoller, who also serves as director. The film is a reunion for the two, as they also worked on The Muppets, which was released in November and Forgetting Sarah Marshall, the 2008 romantic comedy co-starring Kristen Bell and Mila Kunis.

In a box office and season dominated by The Twilight Saga: Breaking Dawn - Part 1, The Muppets have performed relatively well, grossing more than $61 million worldwide since its Nov. 23 opening.

In recent years, Segel, 31, has appeared in, written and produced some profitable pictures, including I Love You, Man, Gulliver's Travels and Bad Teacher. In September, the Los Angeles native kicked off the seventh season of his longtime CBS sitcom, How I Met Your Mother. The show has been renewed for an eighth season.

Meanwhile, Blunt's next big project is the sci-fi film Looper, starring Joseph Gordon-Levitt and Bruce Willis. The mob-infested film, also starring Paul Dano, Jeff Daniels and Piper Perabo, arrives in theaters on Sept. 28, 2012.
