Have you noticed those viral AI videos on social media where a celebrity’s younger version from a classic movie walks side by side with their present-day self? The nostalgic vibes, emotional eye contact, soft winter lighting — everything feels cinematic and heartwarming. No wonder these videos are getting millions of views across platforms.

The good news? You can absolutely create one too. And honestly, it’s much easier than you might think.

In this Mangidik article, I’ll guide you step by step on how to create a viral AI then and now celebrity video using image generation and video animation tools. If you follow this tutorial carefully, you’ll be able to produce stunning cinematic results that look like real movie scenes.

Let’s get started.

Step 1: Generate the Image

The first step is creating a hyper-realistic image that shows the younger and present-day versions of a celebrity walking together.

Below is the exact image prompt you need to copy:

Create a hyper-realistic cinematic scene of the same celebrity in two life stages walking side by side.

Celebrity Name: {ACTOR FULL NAME}
Famous Character: {CHARACTER NAME}
Movie Title: {MOVIE TITLE}

On the left: younger version of {ACTOR FULL NAME} as {CHARACTER NAME} in {MOVIE TITLE}, based on the first reference image, wearing their iconic movie outfit from that role, age accurate, detailed facial resemblance, soft youthful features.

On the right: present-day version of {ACTOR FULL NAME}, based on the second reference image, realistic aging progression, mature facial structure, natural wrinkles, modern outfit that matches their personality today.

Both are walking together on a cozy European street during winter, decorated with Christmas lights, warm golden fairy lights, wreaths on lamp posts, light snow on the ground, cinematic depth of field.

They are smiling at each other, emotional eye contact, warm nostalgic atmosphere, natural walking motion, one arm around the shoulder in a friendly supportive way.

Ultra realistic, cinematic lighting, 85mm lens, shallow depth of field, high detail skin texture, volumetric lighting, photorealistic, movie still, soft bokeh background, 8k resolution, preserve facial identity, highly accurate likeness.

If the user writes "passed away" or "sudah meninggal" after the actor's name, automatically add a pair of subtle, elegant, soft white angel wings on the back of the present-day version, glowing slightly with gentle heavenly light, cinematic and respectful, not cartoonish.

1. Fill in the Celebrity Details

Before using the prompt, replace:

{ACTOR FULL NAME}
{CHARACTER NAME}
{MOVIE TITLE}

If the celebrity has passed away, simply add “Passed Away” after their name. The system will automatically generate subtle angel wings on the present-day version. This detail adds a respectful and emotional touch to the scene.

2. Find the Reference Photos

Now open Google and search for:

A photo of the actor playing their iconic character in the movie.
A recent photo of the celebrity today.

Download both images. Make sure they are clear and high quality because better input means better AI output.

3. Open Imagine.Art

Next, go to this website:
https://imagineartinc.pxf.io/raYAyd

After logging in, open the Image Generation tool.

4. Upload and Configure

Upload the two images you downloaded.
Paste the image prompt.
Open the settings and select the model Nano Banana 2 (you can experiment with other models if you have a favorite).
Set the aspect ratio to 9:16 (portrait).
I personally set the variation to 4 and resolution to 2K, but you can adjust based on your preference.

Then click Generate and wait a few seconds.

Done! Now download the best result because we’ll use it for the video animation.

Step 2: Generate the Video Animation

Now that you have your cinematic image, it’s time to bring it to life.

Copy the video prompt below:

Create a smooth cinematic walking animation.

Both characters are walking naturally toward the camera at slow pace.
The younger version looks up and smiles.
The older version gently puts his arm around the younger one's shoulder.
They briefly make eye contact and softly laugh.

Camera movement: slow dolly backward, stabilized cinematic motion.
Subtle body movement, realistic walking physics.
Winter atmosphere, soft falling snow.
Warm golden lighting, emotional nostalgic mood.

High realism, smooth motion, no distortion, no face morphing, preserve facial identity, cinematic film look.

1. Go Back to Imagine.Art

This time, open the Video Generation tool.

2. Upload and Set the Model

Upload the generated image from Step 1.
Paste the video prompt.
Open settings and choose Kling 3.0 Pro model (you can try other models as well).
Make sure the aspect ratio is still 9:16.
Set the duration to 6 seconds.

Click Generate and wait a few minutes.

And that’s it. Your viral AI “then and now” cinematic video is ready.

Final Step: Combine Multiple Celebrities

If you want to level up your content, repeat the same steps for other celebrities from the same movie. For example, imagine doing this for an entire cast reunion concept. The nostalgia factor increases dramatically when multiple characters are included.

After generating all clips:

Combine them in your favorite video editing app.
Add text overlays.
Insert smooth transitions.
Include emotional background music.

This is where your creativity really shines. You can even structure it like a short tribute video or a “Where Are They Now?” style compilation.
