Good movie and the quote (although set in a fictional setting) is completely true.
1 Peter 5:8
Stay alert! Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour.
2 Corinthians 11:14
But I am not surprised! Even Satan disguises himself as an angel of light.
2 Corinthians 4:4
Satan, who is the god of this world, has blinded the minds of those who don’t believe. They are unable to see the glorious light of the Good News. They don’t understand this message about the glory of Christ, who is the exact likeness of God.
2 Timothy 3:1-4
3 You should know this, Timothy, that in the last days there will be very difficult times. 2 For people will love only themselves and their money. They will be boastful and proud, scoffing at God, disobedient to their parents, and ungrateful. They will consider nothing sacred. 3 They will be unloving and unforgiving; they will slander others and have no self-control. They will be cruel and hate what is good. 4 They will betray their friends, be reckless, be puffed up with pride, and love pleasure rather than God.
