Different international distribution agreements = weird movie bundles & advertisement groupings

Talking about an old Instagram post I found from Sony Pictures Home Entertainment in Spain that features four kinda-random movies that all have different distributors in North America and some other countries, and showcasing my Blu-ray editions of said films. THE INCREDIBLE HULK (2008) (produced by Marvel Studios, with Universal Pictures recieving a presenter credit.) (distributed in most countries by Universal Pictures) (pre-sold to various distributors by Marvel Studios in Japan, Germany, Spain, France, and Australia/New Zealand, with Universal Pictures still retaining their presenter credit.) VENOM (2018) (produced and distributed by Columbia Pictures) IRON MAN (2008) (produced by Marvel Studios, with Paramount Pictures recieving a presenter credit.) (initially distributed in most countries by Paramount Pictures, before switching to Walt Disnsy Studios [under the Marvel Studios banner] in Jul 2013, with Paramount Pictures still retaining their presenter credit.) (pre-sold to various distributors by Marvel Studios in in Japan, Germany, Spain, France, and Australia/New Zealand, with Paramount Pictures still retaining their presenter credit.) TERMINATOR 3: RISE OF THE MACHINES (2003) (produced by InterMedia and C2 Pictures) (distributed in US & Canada by Warner Bros. Pictures) (distributed internationally [outside of the Middle East, Korea, and Japan] by Columbia Pictures) (pre-sold to various distributors in the Middle East, Korea, and Japan by InterMedia)
