This is a verse, I found from about pork:
Leviticus 11:7 `and the swine, though it divides the hoof, having cloven hooves, yet does not chew the cud, [is] unclean to you.
but,
1 Timothy 4:4 "For every creature of God is good and there is nothing to be rejected if it is received with thanksgiving".
So for me, it depends on the people's vision. For me, eating pork is fine as long as it doesn't harm you. As we know, pork is not a healthy food if you consume it often.
About movies and books:
Philippians 4:8Finally, brethren, whatever things are true, whatever things [are] noble, whatever things [are] just, whatever things [are] pure, whatever things [are] lovely, whatever things [are] of good report, if [there is] any virtue and if [there is] anything praiseworthymeditate on these things.
