Carey, who voiced the mayor of Gotham City in the Lego Batman Movie, met up with other star cast members, including Ralph Fiennes (Alfred), Rosario Dawson (Batgirl), Michael Cera (Robin) and Zach Galifianakis (Joker).
Carey has enjoyed only a sporadic film career, despite stellar success as a singer and songwriter over three decades. Her first screen appearance was as an opera singer in the Chris O’Donnell romcom The Bachelor in 1999, and is still most identified with the 2001 musical Glitter, in which she played an aspiring singer. Carey won plaudits for her work in 2009’s Precious, in which she played a social worker.
Carey was in good spirits, having posted on Instagram earlier that day that "I Don't" had become the #1 music video on iTunes as well as the #1 trending video on Youtube on Saturday.
