While Lindsay Lohan is the primary draw of "Irish Wish," the star can't play every role. She'll be joined by a wide range of actors, many of whom are British. Among them will be Ed Speleers, star of many a period drama including "Downton Abbey" and "Outlander," as James Thomas; Alexander Vlahos, also of "Outlander," as Paul Kennedy; Elizabeth Tan of "Emily in Paris" as Emma Taylor, Jane Seymour of "The Kominsky Method" as Rosemary Kelly, Jacinta Mulcahy of "Poirot" as Olivia Kennedy, Carl Shaaban as Jay, and Steve Hartland as Liam. Also joining the cast is the chef-host of "About Last Night," Ayesha Curry, who will play Heather. It's unclear yet who will be playing which roles, so we'll have to wait to find out which British hottie, Speleers or Vlahos, will be Lohan's "one that got away" and which will be the one she's destined to end up with.
