Oooooooh I can almost see the flowers...but keeps seeing Venus Fly traps..............

Ooooooooooooooh Triffids just hit me...............

Day of the Triffids.......now to carry on thinking.............

I've got another one

Two wild west' baddies' go on the run from the law whilst Walter -  a recently discharged soldier looking for work in New York's Catskill Mountains happens across Grogan's Gym, a boxing emporium that helps perfect the "gentle art."  

You have been listening to rawky to much Soozy............I have got to think hard twice now............

Naaaaaaaaaaaaah - it really is easy!

I can't think of two wild west baddies, other than Bonnie & Clyde........(I know!)

Buffalo Bill and .....and......Wild Bill Hicock........

The Lone Ranger & Tonto (I Know!)

Butch Cassidy and the Sundance Kid Galahad?

No ..........here's a clue - they were very good looking!

Yep 

See .........................i don't make em hard!

*takes a bow*

See, I could'nt see them through Alias Smith and Jones

I loved those two ............Pete Duel and Ben Murphy ............i used to love Monday night TV. 

An i makes all the difference when looking at dishy men........

Although on a second look I can see a likeness...........one blonde, one dark...............

Always liked the dark...........Alas or Alias..........

Sorry Rawky...............Gets back to............thinking..............

Okay

-the world's most famous rock and roll band--travel from their home town of Liverpool to London to perform in a television broadcast. - a scary guy with long fingernails terrorises kids as they sleep

Beatle Juice?

A Hard Days Nightmare on Elm Street

You're getting good Soo

 Rawky...............and Soozy 

I don't think this one has been answered in full, though others have gots parts of the answer:

I'll try Terminator 2: Judgement Day of the Triffids

 Correct.

At the Macy's Department Store Thanksgiving Day parade, the actor playing Santa is discovered to be drunk by a whiskered old man ......and then ..........Blanche pays a visit to her younger sister in New Orleans

Try this one:

A writer from the States and a Frenchwoman meet again in Paris leading to a shooting told by the victim.

Miracle on 34th Streetcar named Desire?  

I think the first one is Before Sunset

...hmmm....

I'm gonna have to say Before Sunset Boulevard, but I haven't seen the 2nd film so i can't be sure.

Yep . I don't make em hard . I'm having fun thinking them up though 

Here's one (I'm being quite sly with it too) 

After being bullied her whole life, a meek, teenage girl finally snaps and releases a hidden power within her which also causes a pandemic virus causing 4 people to question their friendship.

You are correct Sunset Boulevard opens with the body of William Holden floating in the swimming pool with the police arriving to investigate the shooting, then William Holden starts to recount the story of show he came to be shot (that's not giving away the plot of the film as this is made clear in the opening scene).

You are aren't you

I have worked out the answer but won't post it yet as your question has only just been posted, but the second film has an indirect connection with a long running series of films and television series

My next puzzle is:

A song of two humans and a presidential illness

This one is tough and neither film is modern.

AARGH!

I think we saw something of the first film at Uni, its silent film isn't it? Grrr!

Haven't got a scoobies on the 2nd one though.

Matilda Carriers? 

 Even though you're, partly wrong, I'm gonna give you a million points anyway

Rawky, you are right in that the first film is a silent one.

Scotty, you are so so close with your answer

I know A Song of Two Humans is its sub-title, so i had to cheat a bit 

Sunrise: A Song of Two Humans .......

hmm...

Matilda 28 Weeks Later?  

Do I get another million points Rawky?
