Seven Keys to Baldpate (1917) 
A writer bets a friend that he can write a 10,000-word novel in 24 hours. The friends takes the bet, and gives him the keys to his Baldpate Inn, which has been closed for the winter, so he can write in complete seclusion. Things start heating up, though, when a succession of people who also have keys to the inn begin showing up.
A rather ambitious endeavour to bring the classic and oft told tale to the screen back in 1917 and the end result is not entirely successful. This is mainly due to the silent nature of the film coupled with zero musical score meaning that often it is hard to become fully engaged with the events unfolding on screen. However, the short running time coupled with the enigmatic George M. Cohan certainly makes this a worthy watch, albeit a slightly flawed film overall.
A difficult one to rate, but I eventually settled on a solid, rounded 60/100
