The film, titled "William & Kate: A Royal Love Story," is set to go into production May 11 in Bucharest. It will premiere on August 13. The wedding itself takes place on April 29.

The movie tells the couple's story, including their time as students at St. Andrews, William's military training at Sandhurst Military Academy, their brief break-up, their engagement and advice from the queen, William's grandmother.

Alexander has been nominated for seven Emmys, winning for her roles in HBO's "Warm Springs" in 2005 and CBS' "Playing for Time" in 1980. She also is a four-time Oscar nominee for roles in such films as "Kramer vs. Kramer" and "All the President's Men."
