Tyrese Gibson and James Franco
Annapolis was not a good movie and we all know it. Apparently, tensions were high on set and James Franco was falling short. In fact, Franco made such a bad impression on Gibson that he swore to never work with Franco again. No one really knows what went down, but Franco was quoted saying that he never "tries to be mean to people." So, take that as you will.
Kate Beckinsale and Michael Bay
Michael Bay isn't a friend to most actors. In fact, many actors and crew members have come out to report his narcissistic ways. Kate Beckinsale was a huge whistleblower in calling him out. She once revealed that Bay told her she "wasn't too beautiful" and that's why he gave her the part in Pearl Harbor. The list goes on with this guy.
