Indy Jones 4 'will rely on seat-of-your-pants action'

Indiana Jones producer Frank Marshall insists the fourth installment in the hit franchise won’t rely on computer effects.

The adventure series has always used real stunt work instead of high-tech graphics, giving them feel of a B-movie, and Marshall doesn’t plan to change the winning formula, according to imdb.com.

He saID: "We didn't have computer effects in those days. We couldn't easily erase things and I think one of the unfortunate by-products of the computer age is that it makes filmmakers lazy.

"You become more creative when you have to hide ramps with a tree rather than erase it later as you can today.

“In Raiders Of The Lost Ark, that's a real ball rolling behind him so Harrison really is in some danger running in front of that;. These are real situations and that adds to the excitement and the creative energy on the set.

“When you start getting into computers, you get fantastical situations like in The Matrix or movies like that. We don't want that, we want exciting heroism, we want seat-of-your-pants, skin-of-your-teeth action.

"We didn't have all the money in the world on the first films and we want to keep that B-movie feel. We want to make Indiana Jones 4 like we made the first three."
