WASHINGTON: Joaquin Phoenix, who won an Oscar for ‘Joker’, isn’t closing the book on his character Arthur Fleck just yet. He is open to the idea of a sequel to ‘Joker’, the Todd Phillips directorial, in which he played a young version of the infamous DC villain. Phoenix, who garnered appreciation for his portrayal of Arthur in ‘Joker’, recently told The Playlist that he sees potential for a follow-up film, reported People magazine, “From when we were shooting, we started to think this is an interesting guy. There are some things we could do with this guy and could [explore] further. But as to whether we actually will? I don’t know.” Rumours of a second ‘Joker’ film have been swirling for a while now but no official plans have been announced yet.
