After the Best Picture mix-up last year, stars Warren Beatty and Faye Dunaway are again expected to present the top honour at the 90th Academy Awards on Sunday. They were spotted rehearsing at the Dolby Theatre here for the ceremony, reports hollywoodreporter.com.

The duo got on the stage in 2017, timed to the 50th anniversary of "Bonnie and Clyde", but after an envelope mix-up by on-site accountants from PricewaterhouseCoopers, the award was mistakenly given to "La La Land" over "Moonlight".
