Anna: You're a good sheep farmer!
Albert: Oh my god, please! I suck at sheep. Louise was right, I can't keep track of them. There was a sheep in the whorehouse the last week.

The movie is set in 1882, however there is a scene where he meets Doc Brown with his DeLorean. Back to the Future Part III took place in 1885.
Ewen McGregor has a cameo in this film after he turned up on set to visit Charlize Theron and Liam Neeson. Seth Macfarlane asked him if he wanted to do it for fun, but it had to be done that day as he was filming nearby. The whole scene was done off the cuff, and he is uncredited.
