The 'Early Man' star shared an apartment with the 'Fifty Shades of Grey' actor in their earlier years in the industry and there was a ''twilight zone'' every night where he had a sudden surge in energy.
Speaking about the living arrangements, he told Good Morning America: ''Basically, it was like living with a puppy because he has more energy than any human being you've ever met. There's sort of a twilight zone between 5:00 and 6:00 when he just goes insane and it was like a puppy.''
Meanwhile, Jamie previously revealed Eddie was ''desperate'' when they used to live together.
Asked what it was like living with the 'Fantastic Beasts and Where To Find Them' star, Jamie said: ''Desperate. We were both very desperate, you know it was slim pickings in those days for work - the idea was you'd come out and all go to the same sort of auditions.''
And with both of them struggling to find work at the beginning of their careers, the pair used to fall out over how many scripts each of them received.
Jamie shared: ''We both had the same agen at the time and I remember on the second day, one of the courieres arrived with 25 scripts and Eddie and I were like, 'Who's it for?' It was for me. Eddie didn't take it that well. He was calling his agent saying, 'Jamie just got a sent loads of scripts.' About an hour later a courier arived with the exact same stack of scripts.''
