Noting how much Jonathan adores his little brother, Hathaway revealed, \"Now Jack's big enough to wrestle with and that's brought a new element to their relationship that's really cute.\"

Hathaway also revealed that she found out she was pregnant shortly before her first fitting with costume designer Joanna Johnston, which forced her to come up with some elaborate excuses to wiggle out of wearing tight-fitting clothes during filming.

\"[Johnston] goes, 'I really want you to have a really tight waist,' and I had just found out that I was pregnant and I was like, 'Mmm, no. No, I don't think so. No,'\" the \"Interstellar\" star recounted. \"She was like, 'Well, why?' And I was like, 'Eh, you know, I just know myself.' I'm scrambling for a reason.\"

Eventually, Hathaway managed to finagle a believable excuse that she wouldn't be \"as free\" in restrictive clothing, so it was best to \"make everything loose.\"
