Maggie Gyllenhaal Blown Away by The Dark Night Costumes

Maggie Gyllenhaal was so impressed by the clothes she wore on set of The Dark Knight she stopped concentrating on her lines.

The actress -- who stars alongside the late Heath Ledger, Christian Bale, Michael Caine and Morgan Freeman in the record-breaking film -- says her costumes were so great she could not stop thinking about them -- even in the middle of crucial scenes.

She explains, "There was this particular jacket I liked. It was a beautiful black jacket with a high collar. It's in a scene where I'm sitting on the stage with Harvey Dent.

"It's a moment of chaos and I'm reaching for him and actually all I'm thinking about was wearing this great jacket."

The Dark Knight, released in the US last week, broke box office records for biggest opening day and biggest opening weekend and also surpassed $200 million in earnings in just five days.
