How I Met Your Mother star and Avengers plot heavy lifter Cobie Smulders is in negotiations to act opposite Vince Vaughn in Starbuck. Vaughn plays a sperm donator who learns he has sired 533 children. Smulders would play Vaughn’s pregnant girlfriend who has heard the story of this prolific sperm donor but doesn’t realize it’s Vaughn. “I thought I was the only one who’s received your donation. And now I learn you’ve been donating all over town. I don’t know where your donations have been. I can’t trust your donor,” she’ll say before storming off in a huff right before the end of the second act. Chris Pratt is also in the movie.
