Sleeper belongs to Allen's pre-Annie Hall movie output when he relied heavier on pure slapstick and one-liners to elicit laughs from his audiences.
The film is early Allen, which is to say that the director is in a far more loose and playful mood than the movies that would come after his Academy Award-winning "Annie Hall."
Woody Allen ("Annie Hall"/"Take the Money and Run"/"Zelig") loads up his futuristic sci-fi comedy with slapstick, sight gags, Mack Sennett-inspired chases and one-liners.
Around the time Annie Hall was made, Allen was transitioning from broad, slapstick-heavy spoofs such as Sleeper and Bananas toward more personal, introspective comedies and dramas.
The comic level of Annie Hall is not as high or frantic as in Allen's Sleeper or Love and Death.
After skewing Russian literature (Love and Death), political leaders (Bananas), and future nostalgia (Sleeper) in broad comedies, it was as if Woody said, “Okay, you’ve seen that I can be funny, now it’s time to get to know me a little bit.”
