I'm always fascinated by the more creative/subtle movie titles that may have double meanings.

For instance:
Return of the Jedi


Rover


Cast Away


What are some other clever movies that may have more than one way to interpret the title?

Psycho - People were supposed to think that title was referring to Janet Leigh's Marian Crane who stole money from work and fled, while we all know what it was really referring it.

And speaking of Hitchcock, Family Plot is as obvious a pun as I can think of, but it does work on both levels.

The Big Chill - Refers to a cold, unfeeling world and also to a dead body.

Do you mean dual meanings within the context of the film or actual double entendre?

"Cop Out" had it's name changed when the studio blanched at the title "Private Dicks." Both titles have double meanings. "Cop Out" is great as it is a shot at the studio.

When I think of double entendre I think of a more sexual/risqué meaning which I'm not necessarily looking for. I'm mostly aiming for dual meanings within the context of the movie.

I thought Cop Out's original title was "A Couple of Dicks" which is a funny but ridiculous title.

I'm ok with examples like "Cop Out" as well. I'm sure there are a few like that. South Park: Bigger, Longer, and Uncut springs to mind as a similar example since the original title was rejected.

I haven't seen it in awhile, but weren't most of the characters cold and unfeeling?

Nope, only Karen's (JoBeth Williams) asshole husband Richard. All the College friends (and the deceased Alex's girlfriend Chloe) come together to support each other in their most desperate time and try to make sense of their friend's suicide.

Would The Graduate count? He graduates from college, and then graduates - big time - into adulthood.

Gravity

I think that's a reach. Plus we never know if Ben is a virgin. He seems flustered and awkward with Mrs. Robinson, but we never know if that's the situation of him being with this long-time family friend more than just the physical act. At least that was my take on it.

Bad Words It's meant to signify curse words and hard to spell words within a spelling bee.

The Straight Story
Main character is Alvin Straight.
It's David Lynch's most straightforward film, narratively-speaking
Yet

Face/Off - The title could be referring to how the two main characters battle against each other throughout the movie, and in another way, the title could also be referring to....aw, crap, I've forgotten what the other meaning of the title was!

Terminator 2! The 2 in the title not only points out the obvious fact that it is a sequel, but also means that there are now two terminators sent back to the past. Judgement Day as used in the film, also has a double meaning.

Also Hitchcock's Young and Innocent could refer to Nova Pilbeam's Erica, Derrick De Marney' Robert, or both actors.

We were??

I think both of those are a stretch. Both Cast Away and Face/Off are great examples, though, particularly in the way the titles are used ("Cast Away" as two words means something more than "castaway", yet it evokes both). I barely remember "Paycheck" and can't really remember if there is a double meaning there.
This is one of those questions that bugs me because I know there must be quite a few titles that really fit the bill, but I'm having trouble calling them to mind.

The Bank Dick

Never mind, it doesn't have a double meaning, it's only referring to penis.

Supersize Me as it refers to getting fat from eating McDonalds food and ordering the larger portions for meals.

Hitch as its the name of the character and it refers to the impediment that keeps the other characters from having sucessful relationships.

Most of the cast is away for much of "Cast Away" as well.

Really? I always thought the double meaning was intended just like that.

My favorite QUICK CHANGE-

Bank Robbery and a change of clothes/costume

Captain America: The Winter Soldier.

Does the title refer to Bucky Barnes' new code name, or to our hero, Steve Rogers? The definition of a winter soldier is "A person, especially a member of a political party or a military organization, who is hardcore, who endures during hard times." Hmmm.

Mike Nichol's "Working Girl" from 1988. The title seems to suggest that a woman working her way up the corporate ladder on Wall Street has similarities to working as a hooker.
