Christian Bale "freaked out" his daughter by keeping his accent for 'Public
Enemies' off set.
The British actor plays FBI officer Melvin Purvis in the 1930s gangster
film and in preparing for his role kept a strong southern accent
throughout filming.
The film's director, Michael Mann, said:

"Melvin Purvis was really a southern
gentleman. So Christian kept the accent for 24 hours a day. It freaked out
his young daughter. She said: 'Daddy doesn't talk like that!' he replied:
'Well, ah'm sorry, mah dear, but daddy's studying for a part, and ah'll be
speaking like this for the next four months.' "

Can you imagine?! LOL!

Michael also revealed that Johnny Depp - who plays the film's leading
character, outlaw John Dillinger - was more influenced by wardrobe, and one
of the most exciting parts of the production was when they got some clothes
which actually belonged to the gangster.
Michael added:

"We got to see some of Dilinger's packed suitcases, which he
had left behind after an escape, and Johnny was able to actually hold his
shirts in his hands.

"They still had the pink paper band around them from the Chinese laundry.
And there were more accoutrements than you'd have thought for a guy on the
run - shaving kit, talcum powder.

"You bet there's magic to that stuff. I'm not superstitious, but I couldn't
help it."

That must be exciting for someone to actually get to see some items that belonged to the man they are portraying in a movie. I imagine that connection would make an actor want to do justice to the part.

What do you think about actors who keep in character even while off set because it helps with their process? You never think about the families right? Imagine what Christian's daughter must have thought for all those months! LOL!
