Just so sleepy at this point.
Even for 1955, 'Francis in the Navy' being the sixth 'Francis' film since 1950 must've been boring as heck. Not that it's a new development, because they arguably all are, but these really are a tedious watch at this point. Francis is again, oddly, in the background.
Despite one more production in 1956, Donald O'Connor decided this was the time to bow out of the series. He does so in relative style, given he portrays two characters - albeit to lame effect, for what it's worth. Clint Eastwood is the pick of the support cast, if only due to who he has since become. He is a little wooden, in what is his first credited role.
I'm actually minorly intrigued to check out 'Francis in the Haunted House' due to somewhat of a mass exodus, with O'Connor, director Arthur Lubin and Francis voice actor Chill Wills all not appearing. Could it be a slight breath of fresh air? I'm leaning the other way, but we'll see.
