Amber Heard is the latest actress to be linked to X-Men: First Class.
According to Production Weekly, 20th Century Fox has "strong interest" in recruiting the Joneses star to play Mystique in director Matthew Vaughn's prequel. Rebecca Romijn portrayed the character in the first three X-Men movies.
Apparently Rosamund Pike is in the running to play Charles Xavier's assistant Moira MacTaggert. MacTaggert appeared briefly in 2006's X-Men: The Last Stand and was played by Olivia Williams. Rumours emerged last week connecting Pike to the part of Emma Frost.
Inglourious Basterds star Michael Fassbender has reportedly declined an offer to screen test for villain Magneto. James McAvoy is the only confirmed cast member, playing a younger version of Sir Patrick Stewart's Xavier.
X-Men: First Class is scheduled to open in cinemas on June 3, 2011.
