In 2018, he produced his first film under his production company HartBeat Productions, Night School. In October 2018, it was announced that through his production company, he has signed a first-look deal with Nickelodeon. Under the deal, Hart and his HartBeat Productions banner will develop and produce live-action, scripted kids content for the network. Hart also has a first-look film deal with Universal Studios.
As of October 2016, Hart was set to portray Santa Claus in Dashing Through the Snow, a planned 2017 Disney Christmas-themed film. In October 2018, it was reported that Chris Rock will direct Hart in a movie based on an original idea by the both of them. The film will be written by Black-ish writer Yamara Taylor and the film will revolve around a stay at home dad who raises the kids while his star CEO wife serves as the breadwinner. The man finds himself in emotional and public turmoil when his wife kicks him to the curb, and they engage in a bitter divorce and custody battle. In 2019, Hart signed on to star in and produce Monopoly, Black Friday, an untitled international romantic comedy, Extreme Job, and Scrooged.
Kevin Hart has also hosted on HQ Trivia and gave away $100,000 to 1 person with Scott Rogowsky on September 26, 2018 which had 699K players.
On December 4, 2018, Hart was announced as the host of the 91st Academy Awards, but on December 6 he stepped down as host in response to public criticism of several homophobic tweets from 2010 and 2011. Hart characterized the protest as non-constructive and stated "If you don’t believe people change, grow as they get older, I don’t know what to tell you". On December 7, he tweeted an apology to the LGBTQ community following criticism that he did not issue one the previous day. On January 3, 2019, Hart announced he was going to reconsider stepping down as host, after openly lesbian comedian Ellen DeGeneres, who has hosted the Academy Awards multiple times, expressed support for Hart to do so and said she telephoned the Academy to ask if Hart would be able to reverse his decision if he wished and, according to DeGeneres, the Academy said he would be able to do so. On January 8, after a backlash for what was perceived as his insincere apology, Kevin Hart announced that he would not be hosting the Academy Awards. The ceremony was held without a host that year.
