It sounds really bad doesn't it? But both we and the Soviet's test flew
spacecraft with this set-up, and it worked fine- there's some shots of
the heat shield hatch on the Soviet VA capsule (the final version of the
LK-1 capsule) on this page:

My other favorite dumb sounding idea? An outward opening exterior
airlock hatch, or outward opening inner airlock hatch- in both cases the
pressure differential is trying to push the hatch open, rather than
sealing it tighter.

What makes this scenario interesting is that the Soviets tried
something
along these lines with Chelomei's LK-1 spacecraft, which looked a
bit
like a Gemini (a Air Force "Blue Gemini" specifically- it ended up
having a hatch in its heat shield as the program moved from lunar
flight
to military space station support)

Interestingly enough, a Gemini boilerplate was flown with a hatch in
the heat shield, to test out the practicality.

Close, it was actually a reflown Gemini.

Reportedly the ablative
material melted over and sealed the gap well enough that it came down
intact. But- I'd have wanted more such tests, on articles which had
been left on orbit for extended times, with exposure to many repeated
day/night cycles.

Not much science data, but a good deal of operational data.

Really? That fact alone is pretty interesting, tangentially. As years
go by I occasionaly discover that more & more flight hardware was
re-flown during the '60s and '70s.

And if anyone thinks that the idea is outlandish, they had better have a
look at the bottom of a Shuttle orbiter- which has three landing gear
bays and two ET propellant feed doors piercing its heatshield, IIRC.
(does the front bipod attachment have a door over it also? I assume it
does.)

It doesn't have a door. It's attached to the orbiter with a shear bolt that
is left flush with the surrounding tiles when the ET separates.

Are there any good films about the Soviet program?

While not a pure-Soviet film, the 3-D IMAX Space Station movie is worth
the effort to see, even if just for the Soyuz launch sequence.

*Very* loosely based on the book, i.e., the title is the same.

As is its predecessor, Mission to Mir.

....And one other recommendation for both: they're only as impressive
as you'd expect when seen on IMAX. Both are available on DVD, but when
played on a normal screen, whether NTSC or HDTV, the impact just isn't
there regardless of screen size. That 60fps really makes a difference,
kids.
