Yes you read right! James Franco has admitted that he struggled to work with some mules after they became increasingly difficult to film with on the set of one of his movies.
The 35-year-old actor says that he got ''stressed out'' working with the animals because they weren't doing what the crew wanted them to do.
Speaking to Nuts magazine, Franco said: ''Once I had to work with these mules ... there was a mule-drawn cart, and they have these scenes that normally would be simple.
''But you only have so many takes because the mules will get tired and you can't abuse animals. And then sometimes the mules don't want to just go from here to here - so doing that was stressful.
''I remember the first two weeks, I wasn't sure if what we were shooting was going to work - and I was dealing with these mules and I got stressed out. I thought I was going to have a breakdown.''
