Elizabeth Olsen has a weird on-set hobby - she likes to take photos of the bruises she picks up while making movies.
 
The star has no plans to use the odd pictures to sue film companies; she just likes to document her on-set injuries.
 
And they were constant while she filmed new thriller Silent House - because she fell over and bumped into things all the time.
 
Olsen tells WENN, "I knocked into many things throughout filming this movie... and I had to film a scene where I fall over and over again with no padding, so I just had to deal with the bruises. I took pictures of all my bruises. I think it's interesting to take pictures of bruises because I like the way they change colors, which is maybe a little weird!"
