The 6th Day

The intro to the film gives us a brief fictional history of breakthroughs in cloning tech. There is an entry on the world's first cloning of a sheep on February 23rd, 1997, which is credited to "Two pioneering scientists Drs. Lerrad Yarg and Phillip Slanigan, both of the Rosaritio Institute." In real life, the two pioneering scientists were Keith Campbell and Ian Wilmut, of the Roslin Institute in Scotland. Although the year was 1996, the announcement was made on February 22nd, 1997, and the name of the sheep, 'Dolly', is correct. Dolly lived until 2003, when she was euthanized due to lung disease and severe arthritis, which were said to be unrelated to the cloning process. Contrary to popular belief, Dolly wasn't the first cloned animal; other sheep had been cloned before from embryonic cells, whereas Dolly was cloned from an adult cell. The next entry reads that the Human Genome Project successfully mapped all human DNA on June 26th, 2000; in reality, this project wasn't finished until April 2003. Lastly, it is stated that a human cloning experiment has failed, and the clone was destroyed by court order. Although several real experiments in the 2000s and 2010s were conducted that created cloned human embryos, these were never grown into live human beings.

(at around 1h 26 mins) When Adam lands his whisper craft on the roof of the building, a security guard comes out to stop him. Adam provides his clearance to be there by presenting him with the contract he signed earlier in the movie. When the guard looks at it, you can clearly see that none of the lines are filled out.

On the Region 1 DVD release, in "The Future Is Coming" making-of featurette, a member of the production crew (Nancy Tate) is credited as a "Cloned Consultant".

On the Region 6 China DVD by Excel Media, the flirting scene is cut.
