Day-Lewis was a dedicated actor. From Wiki:
"Day-Lewis starred in the American film
The Last of the Mohicans (1992), based on a
novel by
James Fenimore Cooper. Day-Lewis's character research for this film was well-publicised; he reportedly underwent rigorous weight training, and learned to live off the land and forest where his character lived, camping, hunting, and fishing.
[27] Day-Lewis also added to his wood-working skills, and learned how to make canoes.
[44] He carried a
long rifle at all times during filming to remain in character.
[27][45]"
To the OP: Congratulations for finding your way back to that rifle. Hope you bring both of them to life.
