The film was re-released in 1974, 1977, 1980[129] and 1993.[263] In 2001, a restoration of the 70 mm version was screened at the Ebert's Overlooked Film Festival, and the production was also reissued to selected film houses in North America, Europe and Asia.[264][265]
For the film's 50th anniversary, Warner Bros. struck new 70 mm prints from printing elements made directly from the original film negative.[254] This was done under the supervision of film director Christopher Nolan, who has spoken of 2001's influence on his career. Following a showing at the 2018 Cannes Film Festival introduced by Nolan, the film had a limited worldwide release at select 70 mm-equipped theatres in the summer of 2018,[252][266] followed by a one-week run in North American IMAX theatres (including five locations equipped with 70 mm IMAX projectors).[267]
On 3 December 2018, an 8K Ultra-high definition television version of the film was reported to have been broadcast in select theatres and shopping-mall demonstration stations in Japan.[268]
