Miscellany

Freestyle MetalX (2003) vs Bulworth (1998)

This has the final say:

Death Pit (1985)

Underworld: Evolution (2006) vs Black Widow #1 (November 2004)

Natasha may have been based on this pose of Melanie Griffith.

Cherry 2000 (1987)

Abduction (2012) vs Tom Clancy's Splinter Cell: Conviction (2010 video game)

XIII (2020 remake) vs Tom Clancy's Splinter Cell: Conviction (2009 novel)

Weird.

Although sharing the same title, video game and book are separate in terms of story, with the latter best described as a semi-prequel.  Subsequent novel Endgame (also published in 2009) retells Conviction. 

Athena (1987) vs Legend of Kage (1987) vs Lisa Lyon²

Psycho Soldier (1987)

²Both snapped by Robert Mapplethorpe in 1982.

A space marine screaming?

Hmmm.

But what the Bob Wakelin is this?

Cabal (1989) vs Zone Troopers (1985)

Well shit.

Alligator (1980) vs Watership Down (1978)

Killer Crocodile (1989) vs Tintorera (1977) vs Jaws - 1975 Spanish comic book 

WTF?

The Witcher (2007) vs Zeewolf (1994)

Shit just got serious.

Wrath of the Demon (1991)

Leave it there.

Attack the Block (2011)

Director Joe Cornish revealed alien bear things were inspired by the cabinet artwork in Space Invaders (1978).

But I see something else.

Another World (1992)

An American Werewolf in London (1981)

And. 

Wolfchild (1992)
Genesis port was presumably modelled on David's carnivorous lunar activities.

Emptiness 

Mantra Surugana (2023)

Stopmotion (2023)

Faceless (2021) vs Seven in Heaven (2018)

The kicker.

Zdzisław Beksiński - untitled 1956 photograph

Now that's amazing.

Time to unload my Big Fucking Gun of knowledge.

Doom (1993)

Don Ivan Punchatz's only contribution to video games is beyond iconic.

Check out cool recreations.

Thor: Ragnarok (2017)

An interesting quirk is that Karl Urban previously starred as Reaper in Doom (2005).

Semper Fi motherfuckers.

Doom: Annihilation (2019)

Doom (2016)

Unrelated media took the piss.

Constantine (2005)

But this is unexplainable.

Eric and the Floaters³

³Graphically modified MSX and Spectrum ports of Bomberman were renamed in Europe to avoid any association with the terrorist bombings carried out by the IRA during The Troubles.

Why is Indiana Jones clone called so?

Who knows?

Cover looks like a poor imitation, but shit was released in 1983, or 1984.

Artist remains unknown.
