When she climbed all over Jeffs preserved corpse
I just looked and Jodelle Ferland has had one amazing career! (I can't believe that same girl who played Jeliza Rose was in Supernatural, Cabin in the Woods, two Stargate series and Bioshock 2 and I didn't recognise her)
...Still, she must've been fairly young during the shooting of this, I wonder if it fazed her at all to be climbing all over the prop of a taxidermied Jeff Bridges... personally I wouldn't want to be in the same room as it plastic or not, let alone lie on it!
