At the end of the episode, Chris incorrectly refers to the Titanic as the Gigantic. Gigantic was the original name of the Titanic's sister ship Britannic, which was renamed following the Titanic's loss. The Britannic served as a hospital ship in World War I, and sank in 1916 after hitting a mine. The Titanic also had a third sister ship, the Olympic, which also served in World War I, but unlike her two sisters, she lived a long life from her launching in 1910 to her scrapping in 1935.
The Titanic set sail from Southampton not London 80 miles away.
When the Titanic comes into full shot, all four of the funnels are functional. However, only three on the ship worked.
This will be the first time Chris will go into the past.
This episode is a parody of the old classic Bill and Ted's Excellent Adventure from 1989
