"Tom talks to Suri several times a day. He misses Suri very much," the source says.
Cruise, 50, has been filming All You Need Is Kill
in Europe, where the source says, he has a grueling daily schedule of pre-production work.
Suri, meanwhile, has a busy schedule of her own now that she's in school. The tot started first grade

"[Tom and Suri] are very, very close," the source adds. "He's up on everything that's going on in her life."
Cruise and Suri last spent time together during a fun-filled
trip to Disney World in early August, which included staying in the Cinderella Castle Suite and frolicking in the waves
and Disney's Typhoon Lagoon.
