Our culture accepts the abuse of the name and few Christians speak up about it. That's kind of a shame. People discuss giving up their lives for their beliefs but they won't even speak up about something like that. They may not think it's appropriate for their child to see at the movies. We also have a culture where it's polite to just step back when we don't like something rather than to speak up if we are offended. We don't want to look like a stick in the mud.
Hollywood reflects our society for sure. Our society is not really interested in islam.
Hollywood takes the most common exclamation among muslims(Allah akhbar) and has turned it into a terrorist war cry, but it's honestly what we have actually heard coming from terrorists. Just as Christians use the name of Jesus for praise and worship, Allah akhbar is something muslims use to express gratitude, satisfaction etc.
