Hollywood superstar Tom Cruise may have recently gone through a painful divorce with ex-wife Katie Holmes but the star is not in a negative mode anymore. According to his co-stars, the actor shows boundless energy and positive attitude on the sets of his upcoming sci-fi thriller Oblivion. His co-star Olga Kurylenko told E! News, ''I was impressed...when he comes on set, he gives you so much energy, you don't even need to drink coffee. He lights everyone up. He's like a sparkle. He's a very generous partner. He gives a lot. He's very professional. He's very nice. Very polite to people.'' The professionalism of Tom can be gauged from the fact that he continued shooting for Oblivion even while dealing with his divorce case.
