Rear Window: Verbs of Perception + Gerund or Bare Infinitive

I like showing classics to my younger students so they learn a little more about movies. Hitchcock's Rear Window is a must to all movie lovers.

Some verbs of perception see, look at, hear, listen to, and feel, along with watch and sense can be used with objects followed by other verbs (base form or gerunds, but not infinitives).

Examples:

We heard you leave. (Okay. Emphasis on our hearing.)
We heard you leaving. (Okay. Emphasis on your leaving.)
We heard you to leave. (Incorrect!)

Other examples:

I saw her go. (okay. Focus on my seeing.)
Look at that man run! (okay. Focus on their looking.)
Sylvester listened to the canary sing. (okay, focus on his listening.)
We watched them play basketball. (okay, focus on our watching.)
We watched them playing basketball. (okay, focus on their playing.)
Trudy can feel the wind blowing against her skin. (okay, focus on the wind's blowing.)
Mr. Todd sensed the lion approaching. (okay, focus on the lion's approaching.)
