Alessandro almost always carries a crucifix and a vial of holy water with him during filming. On occasions where it is lost or he does not have it, he is visibly more disturbed. Curtis does little to help the situation, often just telling Alex to 'get the garlic- I hear that works too!'
Harrison's research takes several weeks to conduct. Even before the location has been fully decided upon, he and his team will have built up a compound knowledge of the area. By the time of filming, he is as well versed in the history as any local expert would be. For this reason, he and Gibson are kept fully separate until shooting begins, which once resulted in Harrison and Levy trudging through a mile of mud just to get to the shoot.
Gibson and Levy once owned a burger shop together.
Daniel Harrison has presented his own research at various seminars around the country. His research specialty is British history over the last 350 years.
