Narrative:

The flight was climbing out and approaching 10;000 ft. The chief purser called to inform us that she could see daylight coming from door 1R coupled with a loud whistling noise. The cabin pressure indications were all normal. The relief pilot went to inspect door 1R. The relief pilot came back and informed me that there was a lot of daylight which was visible at the bottom of door 1R. We informed center that we needed to return. I spoke with dispatch to coordinate our return. After reviewing the landing distance and performance charts for our landing weight; I determined that there was no need to dump fuel. The relief pilot was keeping track of the weight of the plane at landing and said we were about 11;000 pounds overweight. At the gate; maintenance inspected door 1R and determined that there was debris sticking to the bottom of the door seal. The debris prevented the door seal from assuming its normal position when the door was closed. Interestingly; the debris didn't prevent the door from being locked and properly armed.
