There is a statement in the opening credits: "Blackadder Films in association with Baldrick Dodgy Catering Co. presents..."
The opening credits are a series of historical paintings and photographs, featuring Blackadder "Forrest-Gumped" into them..
An orchestral anthem in genuine praise of Blackadder (in contrast to Blackadder (1982) and Blackadder II (1986), which mocked him) plays over the closing credits. It is accompanied by lyrics to sing along to, which the head of Blackadder bounces along to (and the Queen and Baldrick, when the anthem mentions them).
There is a statement at the end of the closing credits: "Blackadder Back and Forth 2... Coming Summer 3000!"
