According to Variety, Geoffrey Rush and Clive Owen have come aboard Working Title and Universal Pictures' The Golden Age, a sequel to Elizabeth.
Thesps join star Cate Blanchett and director Shekhar Kapur, who helmed the first pic.
Blanchett will reprise her Oscar-nominated role as Queen Elizabeth I. The first pic focused on the transformation of the young woman into a steely monarch in the 16th century. Rush will return as Sir Francis Walsingham, who in the first film was the architect of the queen's ruthless campaign to solidify her power and stabilize rule in England.
New film will focus on the relationship between Elizabeth I and Walter Raleigh, to be played by Owen.
Filming will begin in April from a script by William Nicholson and Michael Hirst. Hirst wrote Elizabeth, which was nominated for seven Oscars. Working Title partners Tim Bevan and Eric Feller are returning as producers. Jonathan Cavendish will also produce.
